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.

The phrase a person uses when he/she couldn't possibly care less about what you have to say, yet feels the need to satisfy your "story" with a response. Very commonly received when the person using the phrase feels as if they are superior to you in each and every way, and would like nothing more than to pound your face into the ground.
