A completely worthless game where the sole action is rubbing your finger across your iPhone or iPad screen over a crappy, pixelized picture of a fatass yellow bird until your finger falls off, your screen breaks, or you realize what a douchebag you were for jerking off a picture of a bird in the first place.
John: What did you do last night?

Bob: I played Rubby Bird for four hours!

John: Instead of actually jerking yourself off? You're a douchebag.
