A type of humor only found funny by males. Based on the sound of air emitting from the rectum and the resulting smell. Often replicated by cupping the armpit or the back of your elbow with your hand or by holding two hands up to the mouth. Females DO NOT find it funny.

"ugh, terrible! the guy started using fart-humor on me!"
"eew, only guys think thats funny"
