A person as ugly as a combination of a hippo, guinea pig and frog....

They are generally female but butch, play too much rugby, can't apply make up, cradle snatchers and altogether hideous, annoying, stupid and the most ridiculous excuse for a female anyone will see.
OMG!!! Aisling is such a hippoguineafrog!!!
