just a trivia tidbit ... a male is "troll" ... a female is "trollop".
ROFL
The English noun "troll" in the standard sense of ugly dwarf or giant dates to 1610 and comes from the Old Norse word "troll" meaning giant or demon. The word evokes the trolls of Scandinavian folklore and children's tales: antisocial, quarrelsome and slow-witted creatures which make life difficult for travelers.
EDIT: btw - Seattle (WA) has a troll under the Fremont Bridge. Thankfully, it has been turned to stone, and no longer bothers travelers.
