look up any word, like muddin:
Someone who takes it up the butt.
"Crystal is a slushy butt, that her favorite position."

that feeling of your ass cheeks gliding together on a hot summer afternoon...
bro I got a serious case of slushy butt going on here, I'm gonna go hook myself up with a safety wipe for good measure.

A loose woman that just isn't put together all the way. still better than a dapto.
this woman is still able for sex but you may want to brown bag it, or repress the memory later.
come waddle your ass over here slushy butt...
