When someone is so attractive, that someone else declares they are worth having farts sucked out of their asshole.
When an actor/singer/artist is loved by a fan to the extent of having that fan find them "fart-worthy" despite their physical appearance.
dude 1: "Dude, did you see Pam in that skin tight leopard outfit last night?"
dude 2: "Yeah dude, I saw her. She looked absolutely fart worthy last night."
"Michelle told me she thinks Jay Z is fart worthy because she considers him the best rapper alive, but I think he looks like a camel."
