Phantom Train 

Somewhat like one of the definitions of the houdini where you have sex with a chick doggy style in front of a window, pull out, and switch with a friend which then you go outside and wave to her through the window.

Except in this case you switch with several of your friends and see how many you can switch with before she notices.

Did you hear about Melissa? They ran the phantom train on her and they were 14 deep until she realized what was going on!

Jump on the Phantom Train 

To take a sudden interest in the Metal Gear series and binge-play the entire series in preparation for Metal Gear Solid V: The Phantom Pain.

You know what pisses me off? All these PC gamers trying to jump on the Phantom Train, crying for PC releases of all the previous games.
