its where you have your testicles surgically removed (by a doctor) and placed in to your ass cheeks to supply padding and comfort when I sit or lay

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.
