Passing gas while navigating thru a crowd in bar/nightclub. Derived from drive-by.
"The club was way too busy last night. Left early, but did a viscious fart-by on the way out."

an action by a rude person who walks by another person that is sitting down & knowingly/consciously emits a gaseous odor from his/her anus;
as opposed to a drive-by where the assailant fires a gun loaded with bullets, the fart-by assailant fires his/her ass full of gas
WTF, was I just a victim of a fart-by?
