wet raisin
When you lick another persons (male or female's) dry asshole to provide lube and/or give pleasure to the rectum.
Damn, Gennifer's ass was so dry that I had to give her a wet raisin just to fit it in!
Wet raisin
When a small curd of shit sneaks out before your asshole slams shut while farting. Similar to sharting only you know its got to stay there awhile because you cant get to a place to wipe your ass
I got a wet raisin and its giving me a smelly rash
