BK Myers
Short for “Burger King Michael Myers.”

In the 4-versus-1 slasher movie-themed multiplayer video game Dead By Daylight, it refers to Michael Myers, the killer from the Halloween movies, when equipped with two items that modify his special power: Judith’s Tombstone, which allows Michael to instantly kill survivors he catches once he’s fully levelled up his power by stalking them in exchange for making him move slower, and the Scratched Mirror, which lets him see survivors through walls in exchange for not letting him level up his power at all (and, as it happens, Michael is always slower than normal when he hasn’t levelled up his power yet).
These two items have special uses on their own, but they almost completely cancel each other out when combined, resulting in Michael Myers being permanently slower than the survivors he’s supposed to chase and not even being able to instantly kill them using Judith’s Tombstone since he can’t level up his power. This item combination was nicknamed “BK Myers” by players, jokingly insinuating that Michael can’t catch up to his targets because he’s eaten too much Burger King.

Also known simply as “Fat Myers.”
My friends and I messed around last night in Dead By Daylight. Jamie played as BK Myers one round and still killed me with NOED…
