Alright kids, a jack nasty is where a boy usually high school or younger who can't get laid masturbates 'jacks off' into some tissues. Since he is often not one to properly discpose of them, they drift about the room and eventually make their residence beneath his bed.
The resulting hard, crusty tissue wad peeking out from beneath the mattress... Is a jack nasty.

Person A: What's with the tissues, dude?
Person B: Nothing!
Person A: Man you was makin' jack nasties!
OR:
Man that chick was so fine but I'll never get with her. I cry alone at night and make jack nasties.

This is a sexual move that can be practiced in a variety of ways It’s where you give your partner a dead arm then stick your penis their armpit crease alternatively you masturbate with a dead arm but in the elbow crease for a more sensual experience you may offer this up as an alternate of the ‘handjob’ to give you partner pleasure

when a female picks her nose, hauks a loogie, or some other disguesting act to a part of her body while the male is not looking, before he continues to lick or suck that disired area
