Jass is basically park jongseong/jay’s ass for short, this slang exists to show appreciation for jay’s scrumptious, outstanding, giant, ginormous, big booty😂
Jensen Ackles' glorious ass. Famous for the "Ackles Ass Equation," an actual formula describing the curvature of his booty. Also notable for pairing with the Jitties in The Boys.
jass means ass but no swer
the reason its funny is because some people think it means something good so if you search up jass on gifs you'll find something like "Thats Jass! 😀👍"
