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.

Dave: What's with the big bag? We are only going to watch The Broncos play The Chargers.

Rob: Need Backup Undies

Dave: Got the shits?

Rob: Yeah
