The Flying Bitch Slap should only be used in moments of extreme duress, bestowed upon only the truest of morons.
Say for instance....it's 5:30pm on a Monday. You've just worked a full day and you stop at the grocery store on the way home. There's a lady in line at the checkout in front of you. She keeps running back to the aisles and grabbing more stuff while she waits her turn to pay. She has a cart completely full with Christmas markdowns.... perfume, candy and toys. She makes the cashier check the price of each item, then she contemplates buying each for about 10 seconds and rejects about 1/3 of all the shit she brought up there. She starts making two separate piles of the stuff she is going to buy. The cashier rings up the first pile and she pays with a credit card. Before the cashier can start on the next pile, the lady hands her a $5 bill and asks for ones. You wonder if you would get arrested for whipping a frozen fruit juice can at her head. The cashier starts on the second pile of Britney Spears "Oops I'm Crazy Again" perfume and the Paris Hilton "Skank"cologne. Once she gets the total, the lady pays in cash....and uses the five $1 bills she just asked for from the cashier. It's all you can do not to scream and bash your cart into her, because now she's still standing in front of the cashier, checking her receipts.
Wapow! Flying Bitch Slap.
Or maybe there's this guy at your office. You know that guy? The guy who's in an upper management position? Likes to walk around the cubicles, checking on all his little minions, making sure they're all busy little worker bees? Screams at people because he thinks it makes everyone fear and respect him? Makes dumb decisions and then blames other people for them when the shit hits the fan? Calls the men "babe" and the women "girlfriend"? Makes everyone give him high-fives when they walk by him? Yeah, that guy doesn't wash his hands after he goes to the bathroom. And he just stopped in your cubicle and used your pen.
Aaaand....Flying Bitch Slap.
So tell me....who would you like to use the Flying Bitch Slap on?
