Coostorbro 

It's what people say when they're to lazy to comeback with "Cool story bro".

Person 1: Hey dude, I found a rock!

Person 2: Coostorbro.

Person 1: Wow you're too lazy to comeback at me?

Person 2: Coostorbro.

Person 1: OMFG I'm done.

closterbrobic 

The uncomfortable feeling created in a situation, usually a social gathering involving alcohol, where there is an excess of "bro's" to an uncomfortable extent.

So yeah, I was at the Delt party but I just got too closterbrobic and had to split.

coolstorybro 

Coolstorybro is most commonly said by 12 year old faggots.

It used to be used on the image board 4chan as a reply to a long, descriptive post.

But now the phrase has been spread around the internets by stupid fucking kids who are trying to be cool.

If you see someone typing this, flame them immediately.

Jim: Hi

Faggot: Coolstorybro

Jim: Oh, so you're copying off the other kids now..

Faggot: Coolstory

Jim: Fucking idiot.
