Draco dormiens nunquam titillandus

"Never tickle a sleeping dragon."
The motto for Hogwarts School of Witchcraft and Wizardry in the fictional Harry Potter universe.

Harry pulled out his Latin dictionary and said, "Draco dormiens nunquam titillandus... What the fuck?"

titiot

Any person who loses rational thinking capabilities in the presence of breasts (bare or otherwise)

When I take my friend to the gentleman's club, he becomes a total titiot.

pee-tition

Small wall separating the urinals in the men's room.

I have a shy bladder and hate to use a men's room with no pee-titions.

Titillatio

Performed either during foreplay or sex, Titillatio is when you're titty fucking the woman in question and, assuming her boobs are big enough, she also performs fellatio on you while your penis is between her breasts. A very good time-saving tool for quickies.

Hey baby, i know we're having sex and all but I have to be back at work in ten minutes. Your boobs are pretty big. While you're down there why don't you do a titillatio? That way we can kill two birds with one stone.
