The aromatic vapors of rancid ass transferred to one's finger after digging at the bung hole and scratching the arse. Mung Finger may also occur when one, or more, fingers inadvertently slip through the toilet paper during an ass wiping and touch a dirty bung.
Roger and his friends sat around and watched the pre-season football game. Roger felt a bit of an itchy bum and walked out of the room to give it a quick dig and scratch. Instead of washing his hand and fingers, he returned to the room and swiped is nasty Mung Finger under one of his buddy's nose.
