A bareskin cup is the act of using the palm of your hand in a "cupped" fashion and placing it over your bum hole before you rip a
stinky fart. The fartstink, which remains in the hand in a
concentrated form, is then distributed by opening the hand in front of anothers nasal passage, causing tear-jerking stink. The Bareskin Cup can also be disguised in short as a "bachlor of science (BSc)" for an
unsuspecting victim.
