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.

Hall Costume

A costume you wear to a Science Fiction Convention, ComicCon, or other event just to wear around the halls of the event. You have no plan to enter the costume in a contest (though you might be asked to if they don't have enough participants).
This is just my Space Ranger Flight Suit, a black jumpsuit with a couple of patches on it. I'd never wear this Hall Costume in the Masquerade Contest.

Man in the costume

Figuratively it refers to a well known truth behind some concept (for example, "santa isnt real") that we collectively decide to ignore, because it ruins the fun.

It's in reference to mascot costumes worn by some poor soul to appease the masses, for example the underpaid part-timers staffing the costumes at disneyland

It's like, as a kid, pulling the "no, you didint just kill me cause we are just pretending" card when playing pretend on a playground

Alternatively, man behind the mask
Weeb A: you do know that most weebs are ironic about waifus, right? Only a relatively small amount of weebs actually think stuff like "this fictional high schooler is the love of my life".
Weeb B: Can we please stop talking about the man in the costume and get back to arguing about which underage girl is hotter?

adopted fortnite costume

Adopted fortnite costume is a derogatory way of saying that you don’t belong, or that you are out of style. It is a very popular phrase in gaming, but don’t get hurt if someone calls you an adopted fortnite costume because the person saying it is typically just as bad as the victim.
Kid you’re such an adopted fortnite costume!”
