What is a dopamine brain?

The meaning, where the word came from, and the signs

Meaning

Dopagaki is Japanese internet slang, shortened from "a kid addicted to dopamine".

It describes someone so used to strong signals — short video, social feeds, games — that they cannot wait, cannot stay with anything, and cannot hold their attention.

It is used self-deprecatingly far more often than not. "I am such a dopagaki" is the usual shape of the sentence.

Where the word came from

The word appeared after short video — TikTok, YouTube Shorts — became ordinary. The background is an experience where a strong signal switches every few seconds.

Dopamine is commonly invoked as the brain chemical behind pleasure and drive. From there, dopagaki came to describe a state of being bathed in stimulation with the tap left running.
