1: Somebody who, whether out of boredom, obnoxious tendencies or simply having no life to speak of, causes trouble on a website (eg: by starting arguments deliberately). I know of a website which had to be shut down after some jerk-off started deliberately causing a fuss and turning the various members against each other.

2: A mythological creature often used in fairy-tales such as 'The Three Billy-Goats Gruff'. Generally depicted as humanoid but ugly and sometimes with animal-like fangs, claws or horns.
