Schmup
A friend in a group who when sex is brought up he over saturates the dialogue with how he you all sodomized one particular girl from high school and everyone in the group knows he’s the one who pre-cummed by the time she got around to him, a decade later.
Stiffin
A drunken motion of a dude in your group who’s self conscious about being around 5 foot 5 inches but it’s more because he walks around downtown with his boys in the same bumbling sloppy motion that their 5 inch dick wiggles in his power rangers underwear. These types of people are rumored to grow landing strips in their taint areas.
