[ JAPANESE INTERNET CULTURE ][ ATTENTION ECONOMY ]
The active, ongoing practice of supporting one's favorite idol, VTuber, or character (one's oshi) — buying merchandise, attending events, streaming content, voting — treated as a dedicated hobby/lifestyle in its own right rather than passive fandom.
REAL-WORLD EXAMPLE
"She spent the whole weekend on oshikatsu — merch haul, fan meeting, and a livestream marathon."
LORE & ORIGIN
Compound of oshi (推し, one's favorite/most-supported member) and katsu (活, short for katsudou, "activity"), following the same -katsu naming pattern as other Japanese lifestyle-activity terms (e.g. konkatsu, "marriage hunting"), formalizing active idol/VTuber support into a named category of dedicated fan behavior.
