From the noun, trogg, this refers to being like or similar to a trogg. Specifically, being an unfortunate looking or excessively homely woman. Often used to describe British women, it has some basis in the British slang "trog" (hooligan, lout).
I went to England to visit my sister, hoping to meet a cute girl, but every girl I met was totally troggish.
