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

flopposite

Perpendicular lines:

If lines have the /opposite reciprocal/ slopes, this means the lines are perpendicular.

Given y=-6x-2 and y= 1/6x+4, the lines are perpendicular because the slopes are opposite reciprocal.

Just use a flopposite.

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!
