JKanStyle refers to the Twitch and YouTube personality JKan, a streamer and content creator known primarily for his skill in "osu!", a rhythm-based game.

"JKanStyle" emerged as a community meme and catchphrase that represents JKan’s particular way of playing osu!, characterized by his fast and aggressive approach to challenging levels. Over time, the term also came to be associated with his streaming style—energetic, fun, and entertaining.
