slutty women's Halloween costume formula 

A formula which can be applied in order to make any Halloween costume, regardless of how plain or innocent, slutty enough to be given the "sexy" title by the Halloween costume industry. The formula, from the shoes up, goes as follows: fuck-me pumps or heels, stockings, a short skirt or booty shorts, and a top to indicate what the wearer is supposed to be dressed as. Accessories are optional.

To make a sexy police officer costume, we can apply the slutty women's Halloween costume formula: black fuck-me pumps, fishnet stockings, a blue miniskirt, and a blue button-up blouse with a police badge.
To make a sexy maid: black fuck-me heels, black stockings, black miniskirt, and a white apron.

General Grievous Halloween Costume

For a GGHC you need 2 sets of arms (not yours), 1 pair of legs (again not yours), and a skull (DEFINITELY not yours). None of these body parts should be yours.

Step 1: Look for 4 arms you want and chop them off someone. They'll be screaming in pain as they bleed out. You may want to put them out of their misery so they shut up! Or let them suffer not your problem. Once you do that go to some shack where you won't get caught. Leave the 4 new arms there proceed to step 2.
Step 2: Look for a pair of legs that you want. These should match your arms but it'd be funer to get all of these parts from different people. Cut this person in half horizontally and take their legs. It'd be more realistic if it were a male. But cut their dick off. You have your own so you don't need theirs. When done take this to the same shack as you did in step 1. Leave the new legs there proceed to step 3.
Step 3: This's the final/hardest step. You need to take somebody's head. This'll kill them so look for a black jewish gay man. They need to die! Once you find the BJGM kill him. Decapitate him before showing mercy. When he's dead and headless shave the head down to just the skull. Take the skull to the same shack as the previous steps.
To finish you GGHC you need to put these parts all together. So sew the 4 arms ontop of eachother. Then sew the arm set of 4 to the 2 legs. That will create the body. Finally enter the body and wear the skull like Grievous. Rule #1: Never get caught. Happy Halloween!

Person A "I've built a General Grievous Halloween Costume for Halloween!"
Person B "What do you mean 'you've built'? What parts did you use?"
Person A "It would be better if you didn't know. But it looks sick!"
