mctwisty flop
A fat person failing an acrobatic move and falls to the ground.
That fat guy just did a mctwisty flop while skateboarding and nearly cracked the concrete in the McDonald's parking lot!
KFC McTwisty Flop
A subset of the mctwisty flop, the KFC variant is when a fat man enters a KFC, orders a 16pc. bucket meal, goes to the male restroom, eats the contents, then profusely shits into the bucket. After this the fat man gets in his car, drives to the first checkout window, and throws the bucket of shit through the window.
Man I could really see Jarett pulling a KFC McTwisty Flop tonight after he gets drunk.
