3:makes fart noises with their mouth and/or arm
4: calls everything and everyone they don't like gay

Urban dictionary definition-joe: an incredibly awesome person with a large penis and gets all the ladies.

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.
