A phrase sarcastically used to indicate one's disgust or indifference towards a tl;dr story.

An appropriate response to a story that went nowhere and/or was completely uninteresting.

when someone tells you a boring story you don't wanna hear

Phrase used sarcastically to express a lack of interest in what the other person is saying. Often written on the Internet as, "cool story bro".

A response to a story or piece of information that you find boring, or is too long and you don't want to read it.
One extra note, though. The only proper use of "Cool story, bro" is to say it exactly as it is in the quotes. Any other variation ("Interesting tale, brethren", "Wonderful retelling, sibling") should never be used under any circumstances, and will make you look like a complete failure to everyone who reads it.

The way you begin your story when you are about to lie to your friend or make an excuse.
