The Peanut Butter Cup 

When having anal sex with a fat chick, you pull your dick out and you fill her belly button with the shit stuck to your dick.

So I'm slammin it in her soupbean and I consider going for the pink sock, but since I work for her dad, I decided to just give her The Peanut Butter Cup instead.

butterbutt 

The Butterbutt, or, more properly, the Yellow-rumped Warbler (Dendroica coronata) is one of the most common warblers in North America. In summers, males have streaked backs of black on slate blue, white wing patches, a streaked breast, and conspicuous yellow patches on the crown, flank, and rump.

I saw a butterbutt flitting around in the tree outside my window
