When a jew is performing a 69 and his nose starts penetrating the woman's butthole giving her maximum pleasure.
Rabbi: "Dude I heard you did a 69 with that fat chick last night." Yechezkel: "Hell yeah, I was butt-nosing her the whole time."

A butt bloat is a goof. A person who is defined as a butt bloat is a loser. They suck at everything. So next time you see a person that is not a swanky coug (look it up) tell them that they’re a butt bloat and to make me a sandwich
Courtney: Man, that guy is such a butt bloat
Brooke: I know right!
Courtney: Gawd, I could go for a sandwich right now.
Brooke: I KNOW RIGHT?!?!
Brooke: I know right!
Courtney: Gawd, I could go for a sandwich right now.
