Jane is a tool because she dresses like Avril Lavigne while listening to New Found Glory and Dashboard Confessional just becuase Carson Daly told her to.

A person who thinks they are really cool, when in reality the whole world thinks they are an idiot. This person is actually NOT cool, and potentially has spikey hair and/or wears timberlands with the pants tucked in. This person may think that they are ghetto when they are actually quite white, or they might know all the words to madonna songs.
Hey that kid Kyle is such a tool, he tucks his jeans into his timberlands.
Could you stop being such a tool? You're making me want to slap you.
