Good Troll 

A good troll is one who trolls trollers. Basically, when a troll trolls, another troll defends the one who was being trolled in the first place. A good troll purposely starts arguments with bad trolls. You will notice that a lot of history on that Good Troll's computer is arguments defending someone.

YouTube example:

Bad Troll: This video sucks. Get off youtube, faggot.

Good Troll: You know what really sucks? When a lazy ass guy who doesn't bother to get up and get a life posts not-needed comments because he has nothing else to do. That sucks.

hairy troll brain 

an act in which a man wraps his thumb and index finger around the outside of his scrotum so the tips of his finger and thumb touch.(above the testes but under the base of the penis)After correct placement of the finger and thumb, the hand is moved away from the body in a pulling motion. this creates a "sinching" effect and creates a hairy brain-like object from the testes bunching at the bottom of the scrotum.

because brandon liked to show all of the girls his hairy troll brain, he is now serving 1-15 years in the pokey for sexual harrassment.
