Not to be confused with the attack used by popular Nintendo character Captain Falcon, Falcon Kicking is when a man quickly sticks his foot up another man's gluteus maximus while screaming FALCON KICK! at the top of his lungs. This usually results in the tearing of the anal tissue and bleeding but for some this turns them on even more. Right now this fetish is huge in Japan because every weird and creepy fetish is huge in Japan.
Bob: I'm gonna Falcon Kick you so hard Billy.
Billy: ahhhh so good!
*massive orgasm and blood squirts*
Billy: We should do Falcon Kicking every day! Now get a mop, i'm starting to flood the floor with all the blood coming out of my butt
