The act of filling an empty box full of rocks, then placing it in a location likely to be seen by many drunken college students. This is because, to an inebriated man, it is nearly impossible to resist the urge to kick seemingly empty box as hard as humanly possible. The result is hilarious.

The act of rolling up all the windows of your car to contain blaring rock n' roll music. Gets its name from the similar act of hotboxing your car to contain marijuana smoke.
Guy 1: Dude, pop in the Zeppelin CD.
Guy 2: Better rockbox the car to get the maximum effect.
(Both roll up their windows furiously)
