cheer screening; interactive film screening
A film screening where the audience is encouraged to cheer, clap, or call out, often for anime or idol films. Common in Japanese fan culture.
I plan to go to a cheer screening of an anime film this weekend.
At a cheer screening, it's normal for the audience to get excited and shout out.
Compound of 応援 (cheering, support) and 上映 (screening, showing). A modern term reflecting participatory fan culture.
