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."

The act of letting loose a long string of expletives and curse words. Usually brought on by pain, frustration, or drunkenness. The term "Swear Train" has its roots in 1885 in Topeka, Kansas, when famed Weston Hughes fell off the roof of an express train and swore for a record three hours.
Joe: Did you hear the Swear Train that Bobby let loose when Teresa kicked him in the balls?

Dick: Dude, that must have been one hell of a long train!
