What Is Dopagaki? The Slang for Chasing Dopamine Hits, and Its Origin
Dopagaki ドパガキ · Dopamine kid
You meant to watch one video, and before you know it you’re on the next video, then the next post. Ever seen people call themselves dopagaki (ドパガキ) online? Here is what the word means, how it spread, where it came from and what to keep in mind when using it.
What Dopagaki Means
Dopagaki is internet slang, short for “dopamine-addicted brat” (dopamin chudoku no gaki). It describes a person, or a state, of chasing one quick hit of stimulation after another: short-form video, social media notifications, games, fast-paced music.
In practice it doesn’t refer only to children. Adults use it about themselves too, as in “I can’t wait for long videos, maybe I’m a dopagaki.” It isn’t a serious diagnosis; it’s a word often used as a light self-deprecating jab at yourself for chasing stimulation too much.
But gaki (brat) has a belittling ring. Aimed at others, the word easily becomes an insult, so keep joking about your own state well apart from labeling someone else.
How Dopagaki Is Used
- “I was only going to watch one before bed, but I kept watching. Total dopagaki.”
- “A song that gets exciting right from the intro hits the dopagaki in me.”
- “With editing where the screen changes every few seconds, I watched it all in one go.”
- “I end up following everything: teasers, photos, even clips.”
- “I keep refreshing the timeline to see if there’s any news.”
It’s used when you’re chasing short videos, fast-paced music, an oshi’s latest news and the like, one after another. What it expresses isn’t whether the content is good or bad, but a way of taking things in where you want the next stimulus without waiting. Liking fast-moving songs or short videos isn’t a problem in itself.
The Origin: A Post About a “Dopamine-Addicted Brat”
One big trigger cited for the current usage is a post on X from December 28, 2024. Sharing impressions of how “Lilac,” a song by the Japanese band Mrs. GREEN APPLE, develops, the poster used the strong expression “dopamine-addicted brat” (an X post by @koko_ni_iru4, in Japanese).
What matters is that the abbreviation “dopagaki” itself does not appear in the original post. The post is a clue to the word’s background, but it shouldn’t be confused with the first use of the abbreviation. It is also one person’s impression of a song, not research on listeners’ concentration or brain function.
- The X postA song called a dopamine-addicted brat
- The surveyListed among summer trending words
The abbreviation itself does not appear in the original post.
In June 2026 the word was featured as one of the “real trending words of summer” in a survey of 60 current high school girls. The survey’s publisher reads the list as a sign that words which sum up complicated moods and behaviors in a single phrase are winning support (Joshikosei Lab, “7 real trending words of summer 2026”, in Japanese). It is a small survey of respondents from an official Instagram account, so it does not show the usage rate among young people as a whole.
Dopamine Isn’t Just “The Chemical That Produces Pleasure”
The word contains “dopamine addiction,” but dopagaki is not a medical explanation. Dopamine is involved not only in delight but also in anticipating what will happen next, in learning, and in the motivation to start acting.
For example, when unexpected new information arrives, the brain learns the gap: “that was better than I expected.” This mechanism is called reward prediction error, and it leads to the urge to check again next time (Uchida et al., “Neural circuitry of reward prediction error”). We also explain it for beginners in Why Do People Fall for Their Oshi?.
So watching many videos doesn’t mean you can immediately call it “addiction.” Diagnosing addiction or neurodevelopmental traits is something professionals judge, including the effect on daily life. It’s important not to use internet slang as if it were a diagnosis.
- 01New informationSomething unexpected arrives
- 02The gapBetter than I expected
- 03LearningThe brain records the gap
- 04The urgeCheck again next time
Slang, not a diagnosis; professionals judge addiction.
Why It Happens Easily in Oshi-Katsu
Oshi-katsu has the pleasure of waiting for the next news: a sudden stream, a photo release, concert lottery results, opening a blind-box goods pack. Moments when you want to check “just one more time” in case something nice has happened will be familiar. But the strength of that feeling and the reason for it differ from person to person.
Clip videos and short announcements, meanwhile, are often the entrance through which first-timers get to know an oshi. Being short is not bad in itself. The problem arises when the burden of “I can’t stop,” “I can’t sleep,” or “I can’t do anything else” grows bigger than the wish to watch.
Be Careful When Using It About Others
“Dopagaki” can be a casual self-deprecation, or a word that looks down on a generation or taste.
- Using it about yourself: “I was hopping from one short video to the next again. Dopagaki state today.”
- A use to avoid: “Everyone who likes this song is a dopagaki.”
- Gentler rephrasings: “I feel like chasing short stimulation one after another,” “I’m cramming in too much information.”
The tempo of songs and videos you like differs from person to person. Liking fast development is not the same as having no attention span. Don’t decide a fan’s age or ability with this one word.
About yourself
- Dopagaki state today
- Describes your own habit
About others
- Labels a generation or taste
- Gentler wording is "chasing short stimulation"
Don't decide a fan's age or ability with one word.
If You Feel You’ve Chased Stimulation Too Much
If the word dopagaki helped you notice your state, it helps more to cut back a little on the entrances of stimulation than to blame yourself.
- Choose your notifications — Keep only what you truly want to see, such as your oshi’s official account
- Decide the ending first — Set a break like “three more videos” rather than “ten more minutes”
- Use one screen — Stop, for now, the “second-screen viewing” of opening another social app while watching a video
- Watch long things a little at a time — Even if you can’t finish a movie or a stream in one sitting, it’s enough to enjoy it in pieces
- Put sleep first — Keep your smartphone away from the bed and leave the rest for the next day
You don’t have to move away from what you love. The goal is to get back to a state where you choose when to start and when to finish.
- 01Choose notificationsKeep only what you truly want
- 02Decide the endingThree more videos
- 03Use one screenSkip the second-screen habit
- 04Watch long things in piecesEnjoy movies and streams a bit at a time
- 05Put sleep firstPhone away from the bed
The goal is to choose when to start and when to finish.
Notes From The Oshi Lab: Build Not Just Speed but a Place You Can Return To
Short videos and successive announcements are excellent entrances for new fans to meet an oshi. On the other hand, if you keep raising only the intensity of stimulation, fans keep moving on to the next post and find it hard to have time to savor a single work.
We think both are needed: a fast entrance, and a place where people can stop and enjoy. Put a full video or archive beyond a short clip. Prepare a roundup page after successive announcements. Let people who missed new information catch up later. A design that lets people come back any time grows the relationship with an oshi for longer than a design that holds people with strong stimulation.
