Tuesday Night Disco refers to a special disco in which mostly caters for male homosexuals.

e.g. Telling a guy that they're in for the Tuesday Night Disco would effectively calling them gay.
Guy 1: Did you hear about Pete kissing all those guys when he was drunk the other night?

Guy 2: Yeah I'd always kinda suspected he was in for the Tuesday Night Disco.
