butt-nut 

One who is nuts for butts, that is, an anal sex enthusiast. Can refer to straight or gay people, though it is likely to be taken as offensive when used to describe a gay person.

Remember that girl I started hooking up with at the party? Turns out she's a total butt-nut. Fortunately, she's really anal about personal hygiene.

Butt-Nut 

Butt-Nut is when a male wipes his balls and then his anus.. He then smells it, making two steps one. (Yes ladies guys actually sniff their balls. That tells us wether or not we need to shower.)

Jarred felt lilke he needed to shower so he smelt his Butt-Nut, and decided he could wait another week or two.
