Roxanne was insulted because Mark told her that, "You're like 99% dude." They were playing some word game of some sort and they were a team opposite Lily and Neal. And they beat 'em. (Later on for the rematch, Neal would memorize all the cards so Lily would stop thinking it was some sort of a sign that they weren't meant to be.)
So Roxanne decides to blow off the game. He tells her she's throwing it and she says if she's throwing the game, she's throwing it "like a girl." :D
She was just so insulted about being called a "dude."
