Train wreck

During vigorous sex, a trainwreck occurs when the penis slips out and hits the taint, causing a sudden painful bend.

I ended up in the emergency room with a broken dick after last night's train wreck.

Train-Horn

1. An audible warning device on a diesel or electric locomotive

2. The act of emitting a long and loud fart during an especially strong thrust when having sex.

In other words, farting while running train on someone

Dan and I were having great sex, until his eyes got really big, his cheeks got red, and then he train-horned on me. The smell wasn't too bad, but the sound really ruined the evening.

grain train

A notorious car in a neighborhood that cruises around crowded streets, in which the driver sells pot out of his car. Very easy to find, the "grain train" is usually a dude who will roll down his windo no more than 6 inches from the top, take fifteen bucks, slip you some weed and roll out.

You got any money, cuz the grain train is driving away.

diesel-train

An adrenaline-fueled penis solely focused on hitting the bottom of the vagina.

I think I'm finally gonna give Amber a ride on the diesel-train tonight.
