Max stole your girlfriend a few days ago. You're still anrgy and sad about it, but Max is that guy that every girl wants, so you can't get your girlfriend back.

You're in class, staring at Max, angrily. Then he notices you and smirks.

"Oh?~ Seems like someone's still angry that I stole his girlfriend. U ain't getting her back, dude. Forget her."

He laughs, knowing pretty well he's getting under your skin.
