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.

Get the Niagra Fallsmug. After a male ejaculation, and your pee comes out in two different streams, you must make the ultimate decision: which stream will go in the toilet?
The worst is when the most powerful stream changes to the least powerful and you are suddenly powerwashing your wall with piss.

I had a Niagra Fails today at the toilet, the worst part was it's my grandma's.
Niagra Fails just flooded your bathroom.
