The act of getting so cranked on any form of speed (amphetamine, dexmethylphenidate, methylphenidate, methamphetamine, cocaine, lisdexamfetamine, etc.) that you feel like you're on top of the world, right up until you start to come down and crash straight into the ground like a falling war plane.
Tristan popped a few Adderall and was amping so hard that he yelled "I own this world!", when suddenly he fell down the empire state building and sunk 100 feet into the ground and felt every bit.

Short for amplifiers. They take a small amount of sound from a guitar/electric piano/bass and magnify it.
