Immature 

1. So many teenagers in this day and age who take the time to write immature definitions about s*xual related content, draw men's private parts everywhere they go, think of an inappropriate comment or get an inappropriate meaning from harmless statements by more mature people.

This adjective also describes most teenage boys in general, but I do know a few boys who do not make s*xual innuendos every other sentence.

2. People who think everything they can't do, they don't like, or disapprove of is 'gay'.

3. 'men' who think that women live to serve them.

Mature person 1: hey dude! Want to go---
Immature person 2: get some? Haha alright dude let's go!
Mature person 1: I was gonna say go get some coffee...

Immature person: dude, golf is so gay!

Mature person: just bc u can't do it doesn't mean it's gay.

Immature 

Always seems to be referring to men because they did something stupid-(not smart) having nothing to do with maturity. It is manly use by women referring to there husbands.

"You are so damn immature."
or "He is the most immature person I've ever met."

A young person, usualy a 8-14 year old male that knows 100+ words that mean penis and lives his life just to have them all published in an on line dictionary of slang.

What many high school students are. Nuff said.

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