It is when you shave your balls and surrounding areas and the hair starts to grow back. Like a 5 o clock shadow on your face but the one on your most manly of areas.
My friend took a picture of my cock and balls it was so clear you could see my 5 o cock shadow.
This is when you want to fuck your partner in the ass but are not sure wether or not they have a clean ass. You are not sure if they wiped good or showered after their last shit.
I am going to play a game of Rushit Roulette with my girlfriend tonight because I heard her taking a dump earlier.
