Niagara Falls of Shit 

(n.) this is the result of either eating too much spicy food, having a flu, or getting anally penetrated too hard and/or rapidly. A massive eruption of defecation occurs where shit falls uncontrollably from the asshole. Anywhere from 6 to 65lbs of shit can leave the body.

After anally raping his boyfriend, Glenn pulled out his big jagged dick so fast from Tucker's ass, that Tucker experienced the Niagara Falls of Shit.

Niagara Falls (period)

Niagara Falls does mean a waterfall or city. But it also means a girls period. It is tycially used for girls to talk about among each other without others knowing. It is a nickname for period because for some it might feel like Niagara Falls is coming out of them. Note that you don't say the word period. Just Niagra falls.

"UGHHH that assembly was terrible"

"I know right and I'm on Niagara Falls (period)! So when I finally stood up-"

"I don't need any details."

Niagara Falls, NY

A once elegant very wealthy and sophisticated city, with a famous waterfall, now run into the ground by ignorance, politics and false hope. Pictures today of Falls Street, Main Street, Fourth Street, Park Place and Buffalo Avenue compared to 1880 tell the entire story.

Your family lives in Niagara Falls, NY still? No, we lived in Niagara Falls, thank you.
