Someone who engages in or promotes anti-social behavior as a form of trolling but is generally pro-social in most other aspects of their life.

Differentiated from a sociopath, who engages in anti-social behavior for material gain and other practical purposes as well as sadistic purposes(sadism isn't a prerequisite but it's absence is rare).

Also differentiated from a normal troll who's trolling may or may not be benign. For instance: baiting people in an internet forum with hyperbolic opinions or some variation of rickrolling may be annoying, but isn't considered anti-social.
Billy waited until all the Greenpeace helpers were in view before he ignited the dynamite he had placed in the beached whales mouth. Billy never broke eye contact with the old lady as he started to give a homeless person a bag of food and at the last minute threw it on the ground and started stomping on it. Billy posts videos of women getting beat up and murdered on to women's rights forums and feeds off of the outcry. Billy is a trollciopath.
