27. 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.

1. can't go a minute without making a sexual remark
2. call everything they don't like "gay"
3. openly insult everyone who has a different opinion than theirs, usually with a racial or gay slur
4. have a tendency of shouting words like "PENIS!" in public
5. lack the intelligence to make a formal argument, yet think they're so awesome because they know, as someone before me posted, 100 ways of saying the word "penis" or 100 different sex methods.
6. become alcoholics and do drugs just because "it's cool", without considering that these drugs will cut their life expectancy in half, as well as make them look like total idiots when they're high/drunk
7. call everyone with at least 1.1 times their intelligence a "nerd", because EVERYONE knows that society has deemed it "cool" to be dumb as a stick
8. are the kind that drop their pants on purpose in public, sexually harrass everything that moves, or violate other kinds of dress codes and behavior codes.
Most teenage guys are immature, and not just in real life, but on the internet as well. This site displays perfect examples of immaturity at its best.
