Help please, 10 points defo to best answer?

I'm average at school, clever not nerdy and not popular, and my friend is a little less popular than me but doesn't realize cos he's not in any of my lessons or anything, but he tries to be more popular and calls me a here cos he thinks he's cool. In my lessons this popular girl is like " aww I really love aron" and stuff and I want to get my friend to know without saying too bluntly to show that I'm cooler and more likeable than him.
