pencil stiffy

A pencil eraser, named for being red and hard on the top of the pencil

Jake didn't like how the pencil stiffy would leave great black marks on the page when he tried to erase stuff.

double stiffy

A double stiffy is when two guys get an erection at the same time from the same female.

Damn bro, that was crazy last night. I can't belive we got a double stiffy watching Jennifer Aniston bend over on the set of the TV show friend's.

stiffy tiffy

From the name Tiffany which is the perfect blonde woman. So beautiful and sexy that being around her is so arousing that men always have a stiffy when they are near her. She not only effects men's porn search history. She causes delays in their day after she leaves because masterbation is almost always a must

I was busy but got nothing done because Stiffy Tiffy said hello. So I fapped the rest of the work day.
