A small town in DeKalb County in Indiana where very little goes on. Not the place you want to be at all.
That town was so small and boring I would consider it a waterloo.

A place where slut balls have sex and smoke pot. There is nothing else to do but hang out at the "waterloo mall" (rural king) and get kicked out of McDonalds after getting out of the movies. Sometimes you even get kicked out of the movies if you are making out to much and they think you are going to the extremes ... or if you talk too much ... even if you dont talk at all just give one of the ushers a dirty look and you're outta there. Waterloo is also called "Waterhole" or "The Loo" which means toilet or bathroom in England. Well it actually makes sense because the place smells like shit from all of the farmers fertalizing their land. I am a citizen of Waterhole and let me tell you it sucks. Just don't ride the town bicycle she sucks .. or blows i dont know.

The act of sexually gratifying yourself with a partner while said partner's head occupies the bowl of a toilet as said toilet is being flushed.
Oh man, last night after everyone left I got all Napoleonic with that Melinda chick and ended up giving her the waterloo.

(aka. "University of Wokerloo", "UWokerloo" or simply "UWoke")

If you want the wokest education in the North American continent, look no further. We have it right here at the University of Waterloo. UWaterloo has established a decades-old reputation for being the undisputed intellectual hothouse for future Wokers and Woke leaders alike, whatwith all the misguided hypocritical liberal-political hogwash that started here.

In other words, if you're looking for academic success here, you will only succeed in getting your brain fried, drained or washed by the pretentious clowns who are there to give you the "waterloo" of a lifetime.
"The University of Waterloo: Ideas Start Here" (followed by an uproar from the social justice WARRIORS!!!)
