What is I Know This Guy?
1.
An "I know this guy" story is a bullshit story where one person thinks up something funny, cool, gross, weird, or sexy, but essentially untrue, and tries to pass it off as true by framing it as if it happened to someone they supposedly know. It's similar to the "I have this friend" story, where someone asks for advice about a problem that's really about them but they're too embarrassed to say so. "I know this guy" stories are purely about entertainment, however, not about seeking advice.
Jerry: "I know this guy... he caught his sister having sex with their cousin and two friends in their uncle's bed."
Joe: "Sure, Jerry. You *know* this guy. Riiight."
Jerry: "I swear! It's true!"
Joe: "Bullshit. What was the guy's name then?"
Jerry: "Well I don't *know* him, but I heard about it."
Joe: "Sure you did. Sick pervert."
