Pistachioism

A totally awesome religion in which the practice consists of eating lots and lots of pistachios and having other people mooch pistachios off of you.
The bigger your mound of pistachio shells on your desk, the more impressive and / or hungry you are.
Also commonly done instead of work that we should probably doing, mainly in Science class.

To fuck a girl so hard you leave her quim chafed and red to where it resembles a pistachio.

Used as a literal replacement for "That's what she said" in times when the full statement would be deemed crass and boorish, e.g. when in the presence of your grandmother.
