Jockstrap
From Tardis Wiki, the free Doctor Who reference
A jockstrap was a type of underwear.
In 2009, Gwen Cooper found a Chameleon pretending to be Jonathan Dee's corpse wearing a jockstrap in the middle of the woods. Gwen said that he could be wearing them due to sports, but Martha Jones asserted that "Jonathan" was probably meeting someone for sex. (AUDIO: Dissected)
