Twittok is the side of TikTok that is made to traumatise you. It involves nudity, artistic nudity, pornography and penises. As of recent it has included accounts posting images of Oreos, Apples, Sewing Kits and Jagged Nettles in their foreskin or in their penile slit. It is made to discomfort people and is very much against TikTok's TOS however the algorithm is enjoying sharing the pain with others.
