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 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.
