Backup Undies

Taking more than enough pairs of underwear on a trip due to a severe case of the shits. The occasion is too good to miss so resorting to more undies is the only way forward, it's either this or you use a shart tampon.

Rob: Need Backup Undies

Dave: Got the shits?

Boog: Dude you see that brown shit I think those have been TEST DRIVEN.
Tyler: Man what a steal, let me try them on my face first to make sure they fit right.
Nibslug: All I own is TestDriven-Undies!
