Someone who expends a lot of effort on maintaining the image of being an intellectual. Mostly concerned about the appearance of being seen as intelligent in a voice chat, such as in Discord. The etymology of the word is a hybrid of the words intellectual and illusionist. Someone (probably stupid) that tries very hard to appear smart by doing things like talking over other people. gishgalloping, and using every logical fallacy they can to trick other stupid people into thinking that they've won arguments. They're closer to Alex Jones than an actual intellectual.
People on the Intellectualist server on Discord argue like klingons. They're more worried about winning arguments than constructing good arguments, which is why they deserve the name intellectualist. They're not actual intellectuals. (except maybe for Denzcon).
That basketball enjoyer just stole that lady's purse!
