When you have to fart inpublic, but
you don't want to be embarrassed then
someone does something so hilarious
or extremely funny, you fart during the laugh.

THEN ALL LAUGHTER STOPS AND PEOPLE LOOK AT YOU.
AND SMELL THE ODORIZED AIR.
John: OMGZ That was so funny I took a laugh fart!

Becky: LAWLZZZZZ!!!!!!!! *farts*. woops..
