Top Definition
A loud, moderately unattractive woman who thinks she owns the bar because she's slept with a number of bouncers/bartenders. Named for creatures that frequent the Grog House in Gainesville, FL, but is applicable to any obnoxious drunk woman who you'd like to smack but you know would beat your civilized ass in a fight.
I went out looking for some strange, but the bar was full of nothing but Grog trolls. I'd rather masturbate with sand paper.
