extremely ugly woman resembling something that lives in a swamp

A really ugly girl or woman usually a bit rough or scary looking with bad or disgusting habits. i.e. fanny scratching public farting bogie flicking etc.
The bogbeast put me off my food with her boot ugly boat race (face) and the continual scratch and sniffing of her own rank muff.
