A crossbreed between a tool and a hipster. A toolster would like the Black Eyed Peas, like a tool would, and Steve Aoki, like a hipster would. They would also like the Kings of Leon, like both a tool and a hipster would.
That guy is totally a toolster. He looks just like he got back from a Kings of Leon concert.
Code word used by Bill Murray in early SNL scenes. Wearing sunglasses and acting shady, he'd offer "tootski", then quickly glance around for any narcs, hold a straw to the bump, and say "Go!".
