traitor underwear

a pair of underwear that barely do their job and are a huge inconvenience. Traits might include bunching up around the crotch making it look like you have a public erection, riding up, too open at the crotch, wont stay buttoned, don't have a lucky spot, ect.

I just had to throw away the one pair of traitor underwear I have.
