A slang you say when someone is talking about shit you don't care about, it is unappealing to you and you feel like you are going to split into a freaking coma.

You tell the faggot in a sarcastic manner, "Cool Story Bro".

you all know the definition to cool story bro, but now there's an addition. If you really don't like the story your friend just told, add on "Hope they make a movie about it"
Story Teller: aw man I went to work the other day and this lady came in with her kid... blah blah blah
