Niagra Balls is a variation of teabaging. While similar to teabaging in that the man will slap the person(s) with his balls or dip his balls in the persons mouth, with Niagra Balls the man pee's down his balls while teabaging the person. Thus creating Niagra Balls.
"My testies + My piss + Your face = Niagra Balls. Sink or swim biotch!"
Niagra Balls became in September 2007.
I gave her the Niagra Balls last night. She said the view was breath taking. When you pee while you tea, you make Niagra Balls.
