A morbidly obese whore who is under the delusion that she is actually skinny and that everybody loves her, while all other females on the internet are fuck ugly and have irritating voices. Mupperz is incapable of laughing properly, and instead chooses to imitate a dying giraffe having a four wheel drive shoved up its anus.
Nahhh that's just Mupperz trying to laugh again.
