A large, crowded event during which it is impossible to avoid rubbing your buttocks against another person's body. This is due to the large number of people and lack of personal space.
Concerts, festivals/carnivals, crowded nightclubs, raves, circuit parties and busy shopping days are all considered butt-rub events.
