triple decker peanut butter and jelly sandwich 

The most heinous sexual act. So terrible that your friends can never speak to the girl you gave it to ever again. In addition, they are not allowed to be friends with you for a month. At the end of that month you'll still think it was worth it.

Where's Jim been?
I don't know, I can't be friends with him until August since he gave Jane a triple decker peanut butter and jelly sandwich.
Oh my god! That's awful.

The Peanut Butter has been spread 

A phrase used by a complete moron in a position of power noting that something has happened and is irreversible. Also that the consequences are inevitable.

During a recent conference call announcing layoffs, Vanessa noted that "the Peanut Butter has been spread". Guess she couldnt think of anything smarter to say. I wonder how she ever got her job.

mix my peanut butter 

to "toss a salad" while cumming all over the floor of the room. Difficult to time properly, unless of course you are one of those guys who can get off just thinking about it.

Liia: I let Andrew mix my peanut butter sooo good last night!!
Josh: You are weird.
