look up any word, like rockabilly girl:
(noun) A seated line of 3 or more humans all giving each one another shoulder massages, back-rubs, or any other kind of appropriate massage. The person at the front of the tramapillar is the "head", and the person in the back is called the "tail". While a tramapillar is in session, every member must spontaneously shout "Tramapillar!" approximately every 45 seconds, or that particular individual will experience a deadly, internal explosion.

(verb) to tramapillar
Nick: Hey guys, do you want to form a tramapillar? My back's killing me...

All of Nick's friends: Heck yea, Nick!!!
