A descriptor used to indicate that something is a bullshit knockoff of a part of Japanese culture. Can include poorly drawn anime, weeaboos, bad cosplay, and so forth. When in reference to a person, it should be followed by 'bitch', regardless of gender. When in reference to a thing, it should be followed by 'shit'.

Originates from the DESU meme, which involves spamming forums with the word 'desu' over and over again.
Jesus Christ, those fucking desu desu bitches in the room next to mine are STILL watching Death Note at 4 am.

Candy's drawing of a Yu-Gi-Oh orgy was some desu desu shit. I can't believe she handed it in for art class.
