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.
A toolster is physically a hipster but an undercover tool. A toolster might wear toms, obscure band t-shirts, fitted jeans, beanies, flannels, american apparel hoodies, etc. They will talk about intriguing random facts and life experience. Therefore, they seem deep and thoughtful and will easily trick the opposite sex, when in actuality they are immature and emotionally detached. They might abruptly stop talking to you or be talking to multiple girls at the same time. So beware of the toolsters.
An example text from a toolster might be: "Hey lady or ms. (insert your last name), what are you up to? bout to go drink some wine and get into some shenanigans. You should partake in these festivities."
(also, he probably won't respond for a good 3 to 4 hours)
