Knoxville Knuckleball

When you fist someone with your middle knuckle elevated. It could also mean fisting someone with your class ring on.

I couldn't sit right for 2 days because Tom gave me a Knoxville Knuckleball.

knuckleball wanker

Someone who reckons they're the next reckoning of Cristiano Ronaldo because they once hit a football that moved a bit in the air

'Salim has started wearing Nike Hypervenoms because he reckons he's good enough to play professional football.'
'What a knuckleball wanker!'

knuckleball mitt

a large vagina with bulbous, darkened labia.

Wakefield was pitching for the Sox today and the knuckleball mitt Mirabelli was using to catch him reminded me of your mother's vagina.
