look up any word, like swag:
The time in which people gather in a localized area to play some form of Super Smash. This can be shortened to Smash. It is always Smash O'Clock.
Joe: Dude, it's Smash O'Clock.
Parker: But we have calc class in 3 minutes.
Joe: That's time for at least two 5 stock matches!
