Butt Mayo 

When you bust in her butt and pull it out just in time to dick knife some of that hot mayo in her crack sandwich.

Reese's Peanut Butter Cups And Mayo 

A vile combination that when put together could spell doom for all of humanity.

Man 1: Yo! He's putting Reese's Peanut Butter Cups And Mayo together!
Man 2: Let's get out of here quick before he kills us all!

1. When you wear flannel boxers in the summer and your ass crack sweats.

2. When someone spreads a healthy portion of mayonaise in your ass crack.

It is 95 degrees out and Carl's got some serious mayobutt goin' on.
