When something is extremely unusual and awkward. This term is used when there is no other possible words or phrases to describe the action, person, place, thing, or situation. It is usually saved for the most odd and weird incidents or people. It's origin comes from the very unusual act of soberly shoving four fingers into a drunk, fat girl's anus.
Homie - "Dude, he totally just shoved his whole hand up her asshole."
You - "What the four finger bart sus?"
You - "What the four finger bart sus?"
