A room mate with a particular sadistic sense of things. Normally not found in the wild, a Chainwallet normally majors in history because of their extreme hatred for math or anything imaginary. Has immense amounts of sex appeal, but because a Chainwallet will never leave its room, they are normally freaks of genetic mutations, and never pass on their genes to offspring.

A person with an outwardly dominant, masculine, or aggressive personality, but who also enthusiastically takes on the submissive or "bottom" role in the bedroom.
