St. John's surprise 

To refuse to pay a whore after she has provided you with her services. This is a common practice at St. John's University.

I owed the bitch my last $5 but I decided I'd rather spend it on a couple of Jr. Bacon Cheeseburgers so I jumped out the window and gave her the old St. John's surprise.

Fat John 

A "Fat John" is a code word for the act of taking a poop. No one is exactly sure where the name came from, but it originated in Manchester, NH and has since spread. When referring to a Fat John, the you usually pretend it is a real person.

Person 1: "Dude, Fat John is about to visit me!"

Person 2: "No way! He visited me today, and boy, was he angry!"

Or rather,

Person 1: "Aw jeez, I'm about to be visited by Fat John."

Person 2: "Who?"

Person 1: "Everybody's met Fat John. In fact, most people see him everyday. Sometimes he tries to come in before you're ready, and sometimes he can just explode at you. You usually feel better after Fat John leaves."

Canadian John

a person who lives his life pursuing pussy and sadly gets none, so he resorts to chasing it online.
A Canadian John lives by these rules:

1-hitting a girl up in the DMs.
2-be obnoxious and get rejected.
3-claim you had no interest in said girl to seem less like a loser.
4-attack her appearance or personality.
5-make sure to call her names in group chats making it obvious you don't want her.
6-when confronted with screenshots of you hitting on her in the DMs say you were "just trolling".
7-if someone calls you a loser just say they're "mad".

Maddie: "this guy is being a real canadian john"
Aaliyah: "i would never date John the Canadian"
