21/21/21

A runner's challenge in which the athlete must run 21 miles and drink 21 beers within the 24 hours that constitute his or her 21st birthday.

Alex tried to do a 21/21/21 for his birthday but got overzealous and passed out by noon.

To '21' something is to quit it, to give up on something.

You're outside a nightclub with a long queue, you've been waiting for half an hour and they're still not letting anyone in. Your friend turns to you and says '21 it?', you nod and head home.
