A nerd to a whole new level. (Just like douchefuck takes douche beyond, so does a nerdfuck.)
Not only is a nerdfuck really smart, he's also really arrogant. He's such a narcissist and he talks numbers to seem really cool, when in actuality, it's REALLY annoying.
nerd = smart, most often friendly, not necessarily popular (unless he fixes your iPod)
nerdfuck = smart, wants attention, thinks he's so cool, doesn't shut up about his numbers and shit
Kid #1: Omg, how do you feel about that trinomial? Look at that table, I bet it's width is 425 cm squared! I'm so cool, I can differentiate and my sleep! Yeah! Bet you can't d-rive THAT to the bank!
Kid #2: OMG BILLY JUST SHUT UP ALREADY YOU'RE SUCH A NERDFUCK.
being such a fucking moron... that nerdfuck is all you can come up w/to explain this complete dumbass...
Jay: "Haha! Look! My boogers are green!"
Tyler: "Dude.. you're such a nerdfuck..."
