An adorable and sexy guy's butt. His butt looks like two peanuts squished together, to create a firm and cute butt. I am in love with this guy and his butt is just the cutest thing ever! (Also known as Cooper)
"Would you look at that butt, it is so small, yet still so sexy!"
"That is because he has a peanut-butt!"
