ghoula

An unattractive girl that is likely permiscuous due to her unattracitveness

Man, that girl you had over last night was a ghoula....I know she was down for sex

bar ghoula

A very ugly woman that sits in the darkest corner of the bar, awaiting the last drunk to stumble out the door.

Basically she is an Oklahoma two sacker

Watch out for the bar ghoula's tonight , son!
