Tennessee Traintracks

When you get someone to smile really wide to expose their braces, then rub the head of your dick all over their braces from side to side while blowing on a wooden train whistle.

Guy 1: So what did you get up to last night?

Guy 2: Man, this bitch at the bar wanted me to give her the Tennessee Traintracks so I took her home and blew my wood whistle all over her nasty whore mouth.

Transylvania Traintracks 

Transylvania Traintracks is another term for laced coffee, or coffee with another substance in it. Coffee that has trace amounts of LSD, Cocaine, or any other drug inside of it would be considered Transylvania Traintracks. The reason it is called Transylvania Traintracks is that the Romanian scientist (Romania is modern-day Transylvania) was killed with laced coffee. The "Traintracks" part is there to remind you that it hits you like a steel train.

I just ran a train on those Transylvania Traintracks and I feel like shit now.
