Sun's Out, Tum's Out

Taking your shirt off the second you get within twenty feet of water, regardless of how sloppy looking you are. Dignity and self-respect are meaningless when practicing 'sun's out, tum's out'.

Dude 1: Jody can't go near a body of water while keeping his shirt on. Check him out over there in the kiddy pool splashing water on his gut.

Dude 2: Sun's out, tum's out bro. Stop shaming.
