Brush him off

"Whatever, Davis," you say, rolling your eyes and walking away.

"I thought you are a dude," Davis replies, chuckling like a douchebag, and following right behind you. "But now I'm surprised you're not carrying a purse and putting on lipstick!"

You just roll your eyes again, and keep walking.

"You're just gonna take that?" he scoffs. "I insulted your manhood, dude, a real man wouldn't take that!"

"I'm not gonna fight you, Davis," you sigh. Davis, being one of the strongest and most fit guys in school, is constantly getting in fights to show off his strength. You've seen some desperate attempts to get people to fight him, but these 3rd grade-level insults are the lowest you've seen him sink.

"Not gonna fight, huh?" he says. "Well, then you're a weak little bitch. And, if you don't fight me, I'll make sure everyone knows it!"
