Flump

A flump (fl-uh-mp) is generally used to describe a woman, whom at first glance, is considered to be very unattractive/ undesirable, ugly, disgusting, and mostly someone whom you would not sleep fuck with. However at a second glance, nearly immediately after the first glace/ initial reaction, you have a sudden realization that you would indeed still have sex with her and/or "wouldn't kick her out of bed".
