1.
A woman who is generally not concerned with her appearance and doesn't make any attempt to look womanly or sexy. Frumps are very common in the Seattle area. They need not be overweight but commonly are somewhat "doughy" and are characterized by lack of makeup (except for ugly art-school or Goth-style makeup), poorly-fitted, unstylish clothing, general lack of muscle tone or a tan. They sometimes wear very bright red lipstick or substitute teacher cat-eye glass to make themselves even less appealing to men although they are not dykes. They'll often complain loudly that they can't find a man yet make no attempt to present themselves in a manner that might attract a man (showing skin or cleavage for instance). They might even be somewhat attractive (do-able)if they made an attempt at dressing better and wearing makeup and/or a better hairstyle.
Wynonna Ryder is an example of a well-known frump (don't you hate the way she hides those awesome gland bags of hers beneath baggy shirts?)

I saw a group of frumps out for a walk wearing parkas and "Seattle Sombreros" (an ugly Gore-Tex rain hat) walking at Pike Street Market on a rare sunny day in Seattle.
