niagra 

Slang for Viagra, Cialis or any other Erectile Dysfunction Meds. It is a combination of the word Viagra, Which is the most well know ED pill, and Niagara as in the popular water falls, because of the copious amounts of Jizz one produces while taking the Viagra.

-I took a couple of "Niagras" last night before banging the old lady, shot so much spooge I thought I'd need an I.V. afterwards.

-Don't take any of those "Niagras" tonight, my snatch is still sore from last Tuesday!

Niagra Balls 

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.

Niagra Runoff

a sex act where a woman or man with a trachiotomy opening in their throat is performing fellatio. The man ejaculates, the partner swallows and the semen subsequently goes down the throat and out the trach opening, gushing much like niagra falls, with the runoff making its way down the chest.

Hey man, I fucked this chick that had one of those voice boxes, right? well she had some sorta surgery & has this hole in her throat. She sucked my dick & she swallowed. She said it wasn't her first Niagra Runoff.
