Sam: Dude wanna go have a mud fight!
Kevin: Your so immature, thats for little kids.
Sam: Fuck you at least I'm not an asshole.

In a generic age-irrelevant view of the concept: someone who wouldn't or can't get himself to do what they know is the right thing to do.
Someone who likes someone else but wouldn't act upon it; simply cause they are too immature to do what normal people would do.

Just because you're in high school doesn't mean people cannot be immature. Maturity is nothing but a mere joke.
