turtleneck butt 

When you go a month without pooping, and the turd is so huge it stretches you hole so far that afterwards it hangs down loose like the collar of a turtleneck sweater.

I went to camp and couldn't poop for a month. When i finally did, it stretched my asshole out so badly now I've got turtleneck butt.

Turtleneck Sweater 

(n.) A strategically designed sweater that has a piece of fabric at the top which hugs fabric completely around the neck. Mostly worn more recently by snobby artists (usually accompanied by a beret also black) or mom's over 35. However, the sweater originated to solve an age old problem of hiding hickeys. The neck is one of the most common places for visible hickeys to appear after a passionate make out session. The next day when you have to have dinner with you parents (or maybe even grandparents!) the hickey will make them think you are some kind of sex fiend. A fashion designer had this problem and after realizing all of their scarves were dirty (don't ask, that is more sex fiend stuff) quickly sewed extra fabric on top of an old sweater to completely conceal around the neck and thus the hickeys. Now men and women can wear hickeys around their families and everyone will think they just have no fashion sense.

Girl: "Tomorrow I have to spend Christmas visiting relatives."

Guy: "So no Chistmas Eve necking then?"

Girl: "Oh we totally can neck all night, I have an ugly Turtleneck Sweater I can wear!"
