look up any word, like dirty sanchez:
 
1.
A very smart person (usually with an IQ over 130) that doesn't act like your typical nerd. They don't give a shit about race, most have friends from a variety of races, or others religion, e.i. one could be christian with an atheist friend. Generally avoid the populars. Usually wear clothes more toward comfortable than fashionable though they can be fashionable. Intellectual Badasses (or IBAs) usually dont fit in with many other people than other IBAs. They hate posers (e.i. Their theme song says "we don't roll with the grills; we got braces on our faces) Could be precieved as normal but everyone know who they are because they're the group that's always laughing geniunely and cracking perverted jokes. Usually envied by populars/bitches. Top of the 'food chain' but don't really give a shit about it. Stick together like real friend should.
Bitch: Ugh they're such losers!
IBA: Nah we're bad ass. Intellectual badass bitch. So step back before I make you!

2.
Someone who is so smart i.e. a nerd, that they could single handedly save all dumb peple from a chat life.

Because let's face it, Where would the world be without nerds? Nowhere, that's where. Without nerds, we'd still be lighting our rooms with candles, having leeches stuck to us to cure disease, and taking dumps out of our windows. Sure, we may be unfit for female consumption(and vice versa), we may spend hours arguing if Star Wars is better than Star Trek, and we may have the social skills of a chimpanzee, but it's high time that nerds were recognized as the true intellectual badasses they are!
Nerd : I have an IQ of 145

The proper term for a 'nerd'; someone with a high IQ and a broad vocabulary; nowadays commonly accompanied by a kickass body plus a pair of glasses.
