“Infamous troll who ruled over/participated in a domain that at any given time consisted of 20 or 30 board members. ___________ kept them on their toes, and was best at believing he/she was the best at everything”?
What an accomplishment that would be!
In Internet slang, a troll (/ˈtroʊl/, /ˈtrɒl/) is a person who sows discord on the Internet by starting quarrels or upsetting people, by posting inflammatory, extraneous, or off-topic messages in an online community (such as a newsgroup, forum, chat room, or blog) with the intent of provoking readers into an emotional response or of otherwise disrupting normal, on-topic discussion, often for the troll’s amusement.
Mommy, mommy! I wanna be a gaslighting troll when I grow up, and maybe even have my own board one day. Will you and Daddy support me in my dream? Please?
