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!
