The 'Cool Story, Bro' meme is a staple of internet sarcasm, used as a dismissive response to someone telling a long, boring, or unbelievable story. While the phrase gained traction on message boards like 4chan and Something Awful in the late 2000s, it became iconic when paired with a still image of Hercules from the 1990s Marvel animated series, 'The Incredible Hulk.' The character's smug smile and thumbs-up perfectly capture the essence of insincere interest. Since then, it has evolved into a universal shorthand for 'I don't care' or 'That didn't happen,' remaining one of the most effective ways to troll overly enthusiastic storytellers online.
