A response to any of the comments made by Junaid Yasin, a brown senior at Parkway West High School because everything he says has completely no relevance to the current conversation. Cool Story Bro is also known as the "ultimate shutdown".
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".
A suitable way to articulate your lack of interest in a male after he forcibly thrusts his erection in the direction of your butthole whilst spooning with him; also an appropriate response to a photograph of a boner sent via text or E-mail.
An adaption of the infamous cool story bro
Chess: Yeah so I was totes spooning with Seth last night, and he kept pushing his boner into my ass. I was like cool boner bro.
Anke: Dude, I said that when Jack told me he was hard.
A phrase used by awesome men with 7in.+ penis' and meant to be used when women talk about long boring stories when trying to watch football or doing something more important.
