Immature is a person, usually 8-15 year's old, (and mostly male) who think sexual and inappropriate things are funny.
This drives me totally crazy, when your the only kid of you age that is way more mature then everybody else areound you (like me)
They call everything they don't like gay, or retarded, and anybody smarter than them a nerd, because they are to incapable of realizing that they are stupid, and (not to be hypocritical) retarded...
-Immature person- You got high honor roll in school? Hahahha! Your such a gay nerd!

-Civilized person- Your immaturity is making yourself look bad...Not me
