Wet Sleeping Bag

When a woman has a Uterine prolapse (uterus falls out of the vagina), but she's white trash and keeps shoving it back up inside herself with hopes of popping out another kid.

"Damnit Cathy, you sneezed and your puss popped out and it looks like a wet sleeping bag!"

"Damnit Karen, put your wet sleeping bag away, the floors wet again... grab a mop!"

"While golfing yesterday, Tina left a wet sleeping bag in the porta poty."
