Originated in Louisville Kentucky. FLuP refers to "Far Left Pedal", or "clutch" in other words. If something is "flup", it is very clutch.. life-saving.. extraordinary.
(In a game of Flip Cup) "Slim flipped his cup before that other dude... he's fuckin' flup!"
"Chuck Norris is the most flup motherfucker on the planet."
"Thanks for taking the blame on that one... that was flup."

Get the Flupmug. Flup flups are a rare and heroic breed of kittens commonly found in the western regions of Europe and Wonthaggi.
They are too highly intellectual to walk so they therefore "flup flup" about on their own conditions.
