What is Assblast?
1. When you have to take a shit really bad and it comes out as a runny burst.
2. Having sex with someone in the anus and having a lot of fun in the process.
1. That asshole Matt left an assblast all over my toilet!
2. We had a real assblast at the party last night. Matt's ass is going to be sore for a week!
When drilling a girl in the ass and finally releasing, if you wait 5 minutes she will perform an ass blast covering any and all substances around with cum and shit.
I kicked that bitch in her stupid face because she assblasted me.
A loud, odiferous, noxious, and entirely pleasing emission of gases and various chemicals and excreta from one's nether gate.
I gave a satisfying assblast in the crowded elevator and caused a panic between floors 11 and 14.
