Bathshroom 

The word bathshroom contains the words "bathroom" and "mushroom." These fungi appear in the most discreet of corners, usually in bathrooms where moisture and mold collect and sprout colonies of the most decrepit kinds.

You know you have stepped foot in the nastiest of lavatories when you stumble upon some tile fungus. "I swear I saw bathshrooms growing in that bathroom while I was taking a leak. Somebody get these people some Mr. Clean!"

Bathroom 180 

When you walk into a public restroom, and immediately have to turn around 180 degrees and walk out due to some foul stench.

Occurrences are enjoyed when you repulse someone, as you're still sitting on the throne conducting your business.

I was dropping a deuce at work and I heard someone come in the bathroom and almost choked. They quickly did the bathroom 180.

upstairs bathroom effect 

A phenomenon in which an occupant of an upstairs bathroom is unable to hear what individuals downstairs are yelling up to him.

Marie: (To Kenneth) Darling, your brother is on the telephone!
SILENCE
Matthew: Alas, dear; he is using the upstairs bathroom and is thus unable to hear that which you are attempting to communicate to him. He may as well be deaf. This is a superb example of the so-called upstairs bathroom effect.

LSN bathroom 

The place where all the wild ass shit goes down. There are many WILD stories about the LSN bathroom but for right now we'll only stick to one. This is the place where a urinal was stolen from a high school bathroom. Now I know you might have a few questions regarding how it happened...unfortunately I can't answer those questions because I don't know the answers to them myself, but all I do know is that it did happen. I'm sure LSN was fucking pissed and was wondering why tf one of their tard ass fucks decided to steal a urinal but it's probably their fault because they didn't properly install the urinal so it was able to be ripped out and finessed. The boys bathroom will always be wild and the shit that happens in there can never be topped...

Student 1: Yo did you know it was Mike Carlson who stole the urinal from the bathroom?
Student 2: No way wtf the LSN bathroom is wild, how??!!!! Wait, isn't that the dude with a tard ass uncle too?
Student 1: Yea dude, he just took it and walked out of the building, and yea, he does have a tard ass uncle

avetard bathroom 

NEVER GO INTO THE BATHROOM ON THE FIRST FLOOR AT THE AVE! This is the bathroom where niggas who can't hang will go throw up and make a huge ass disgusting mess before passing out. Once the bathroom is covered in vomit, an elephant will go in the bathroom and throw neck. This will lead to person receiving neck, also vomiting. Basically, it's normal avetard shit but it's just taking place in the bathroom.

Bruh, they went into the avetard bathroom to fuck, but the bathroom is covered in vomit and smells disgusting.

bathroom yellow pages 

A Toilet paper roll in a bathroom stall that has been intentionally drenched with piss. Main reason for doing so is to make an unpleasant shitting experience for the next patron.

I hope no one has to take a shit in that stall tonight. All I left them to wipe with was the bathroom yellow pages.
