Cool Story, Bro! is a sarcastic phrase posted on message boards and stories on many sites, indicating that the post was boring, too long to read or pointless.
The phrase was apapted from the 2001 movie Zoonlander, wher Owen Wilson's character (Hansel) explains a long, winded story about a hallucination. Then, another character, "Olaf" yells, "Cool story, bro!" The saying has been know to exist as early as July 18, 2008, used on the /v/ board on 4chan.
