When you are calling bullshit on someone, in essence saying you don't believe their incredible story. So named for the balloon boy story that ended with Falcon (the boy's name) having been hiding in the attic all day while rescue workers chased the balloon across the country.
Matt: So, I was at the bar last night, and I walked up to hit on this girl. She and her two female friends thought I was hilarious. We went back to my place and I fucked all three!

Mike: And you know what I heard? There's a falcon in the attic!

Matt: Huh?
