After giving a great insult that totally makes your friend speechless you
slap him with "Roll Credits" meaning that it's over, the audience is leaving and nothing else can be said. It would also be proper to use your hands to demonstrate the
rolling of the credits on a screen.
This is also proper to use to term the ending of anything: a night out, a pickup
game, or even a relationship"
"Yeah well you're ho is
ginormous" "Roll Credits"
"We just rolled credits on y'all"
"It's over, Roll credits"
"I gotta roll credits on this, gotta an
early meeting"
