Fart tent

At night, a person knows he or she let loose one of the worse smelling farts of their life so they pull the sheet over their partners head. The partner is trapped, but the smell is so bad they wake in a panic to flee the covers.

Last night I had the stinkiest fart of my life but couldn’t place the smell. Had to give the wife the old fart tent. She woke in a panic and couldn’t escape the covers.

swollen in the back

Another way to say some one has a large booty

"Damn that girl is swollen in the back"
