High school (and sometimes college) boys who like sports, are generally huge assholes, get really drunk, say things like "damn son!", and are disrespectful to girls.
Typical nardy conversation:
Nardy 1: "Dude, I was so drunk last night!"
Nardy 2: "I know. I fucked insert random girl"
Nardy 1: "Damn son! Who was it?"
Nardy 2: "You know, just some bitch."

Typical girl conversation:
Girl 1: "Hey, I'm having a party tonight."
Girl 2: "Ew, can we not invite the nardies? I'm actually trying to have fun."

A word used to define someone who is considered cool, in the context of one's name.
Hey, Ben Fenner is pretty cool.
How cool?
He's not a Nardi, but he's still cool.
