A game you play in which you stick your finger up your butt a little bit, then you sneak up on a friend & jab that finger up your friend's nose while you shout "Buttsmell! Buttsmell!"

Your buttsmell will wipe from your finger to your friend's nostril, & the smell cannot be gotten rid of. It has to fade away.
lol I buttsmelled you, & you threw-up from the stink. You'll remember my buttsmell forever now.
