A game popular with college fraternities, in which it is necessary to have a strong guy enforce the rules:
Everybody gets naked and shoves a pimento-stuffed olive up their asses, then tries to deposit them in a milk bottle on the floor. If the contestant misses the bottle, he has to eat his olive. If he kicks over the bottle, he has to eat everybody's olives.

A portmanteau of carpe diem, a Latin phrase that means “Seize the Day!” and DM, which stands for Direct Messages. This word means seizing the day via DMs.
