Flappy Bird 

A stupid ass lemon with fucking Pringles for wings. Flappy Bird flies through a shitty Mario-esque world, trying to dodge the warp tubes, while failing miserably to keep his Pringle wings flapping.

In other words...a stupid game that was created by Satan to piss people off.

John: Oh hey whatcha playing, Sean?
Sean: Stupid Flappy Bird...this son of a bitch is hard to play! I barely just hit 13 points...oh goddammit! Fuck you Flappy Bird!

Flappy Bird 

You can use the phrase 'Flappy Bird' as a code word when you are talking about someone who is stood or sat next to you without them knowing you are talking about them. You normally call someone by Flappy Bird if you don't like them so when you say, "Flappy Bird is a n*b!", the annoying person just thinks your talking about the game. Simples!

Kid 1: (Talking about Rohal) Flappy bird is suck a w*nker.
Kid 2: Yes I know.
Rohal: Flappy Bird is not that bad.
Kid 1: Yes it is.
Kid 2: yea

Flappy Pappy 

When a naked man does consecutive standing pelvic thrusts into the air, which results in a between-the-legs swinging; pendulum-like motion where both balls, and penis simultaneously make contact with one self, causing an audible phenomenon.

When Richard found out the baby wasn't his, he did a flappy pappy for damn near ten minutes!
