Happens When a man, usually Canadian, kneels face down into a pillow while another man puts peanut butter and jelly in the crack of the first man's ass, then proceeds to allow a pet of choice to like it off, usually a canine of sorts.
He will be afk for the rest of the night, he's getting the ole CanadianPB&J!
While traveling outside of Canada, a Canadian may introduce themselves by grabbing the other person's ass, balls or vag. Most commonly used by crazy drunk Canadian girls on vacation.
Hi, my name is Nicole (said while reaching around and grabbing the waiter Jose's ass with a firm Canadian Handshake).
Joe just pulled the Canadian Slip when he transferred a call to a co-workers desk for no good reason. He also pulled a Canadian Slip when he took an hour dump after taking an hour lunch.
Weary after long hours of traveling and installing the exhibit, the interns thought they would take a canadian lunch back at the hotel, to rejuvenate themselves.
