a really disgusting girl who calls you a compulsive liar,
who's really the one who's lying.
She'll elbow you in the face for telling the truth about her boyfriend,
and she'll just try to make your life hell.

Usually a tall fat disgusting girl.
"Oh my god, have you seen the new girl, shes tall and hideous!"
"That's what you call a pigbeast
