What is F-bird?
1.
when in front of someone that you are keeping a secret, one of your dumbass friends drops the info on them. From this new known information you either look like a complete pussy, or your significant other knows you cheated on her skank ass.
in a group setting with your friends and perhaps a girl that you are interested in or someone that you are trying to impress. your friend accidentally says something about last weekend when fucked her sister or best friend. "Dude i can't believe you dropped the F-Bird in front of her."
