trainus

An anus that looks big enough to navigate a train through. An anus that resembles a tunnel going into a mountain.

I was going to fuck the bitch but as I tried I accidentally fell in her trainus and had to be extracted by the jaws of life.

Trainus

An anus that has been trained to fart as soon as a wife and or girlfriend has left the room.

A fart snuck out of Tyler's trainus as soon as Bailey left the room.
