The sexual act where you spread your partners rectal flaps with the knuckles of your index and fore finger, then cum with the screwball on a count of two balls and one strike.
The bases were loaded so I slipped her a knuckleball. Garth, she definitely won't be walking home any time soon. Two balls, on strike, and I'm out - she was like WTF!

A crazy shot in soccer where the ball moves side to side up and down and has and an unpredictable movement and is the Goalkeepers worst nightmare! Most knuckleballs only Alem Torlakovic ( Soccer Skillz82) can do!!

A baseball pitch which follows an unpredictable path. Very difficult for batters to hit and pitchers to throw. Only a handful of pitchers in the major league actually utilize it.

When engaging in intercourse with a woman from behind in the vagina, a quick, sudden and forceful penetration of the anus. Often occuring as an accident, it may also occur as a "How do you do!" to simply ring her bell.
Last time I was bangin'-it-in with that bitch, I gave her a donkey punch, so to spice things up, I gave her the ole' Arkansas knuckleball!

Type of kick used in soccer or Iranian Jujitsu. In soccer, when the ball is hit with such force and velocity that it can rip through the goal’s net. In fighting this move is when you do a kick spin and drive your right foot right into your opponents balls, rendering them incapacitated.
Dude1: Hey man wtf happened to Jack?
Dude2: He thought he was tough so I had to give him the old Iranian Knuckleball!
