Get the Cool story, bro mug.
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.
Me: Yeah, so I was at the mall eating some corn dog when this guy walks by.

You: Cool story, bro
