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."

Get the nardies mug.
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.

Probably the coolest last name out there. If you ever meet anyone with this last name, you know they are twice as cool as you.
Whoa, his name is George Nardi?
