janny, janitor, is used to complain about overzealous or temper tantrum throwing mods on imageboards, its effect in places like those and here because of the attitude against restrictive rules making mod a less respected and thankless position then even other parts of the internet. "he does it for free" is part of a pasta that mocked a perceived ego of mods by comparing their work to unpaid janitorial work. if it sounds dumb to you its probably because the idea of modhood being an achievement you brag about is an alien idea to you, as is the idea of a mod as a martyr who gives up some time or parts of their anonymity to make a site better and therefore deserving of more respect than posters in the form of more allowances to wave their power or win arguments.Jokes aside, cuck will definitely survive because it's become synonymous with "bitch" "cunt" and "faggot", serving as a catch-all term for people that you don't think highly of. Simp seems much more like a fad term like "epic" and I forsee it fading in time. Gunt is situational and will have its applications every now and again. I'd never heard "janny" before simpgate, but I'm of the mind that it's exceptional and the only reason it has any staying power at the moment is because it triggers Dear Feeder so much.
simp is probably the one with the least staying power but it always was going to be, i dont think anyone will be killing themselves because the share price of simp collapses. i think itll be more the term more than the idea thatll falter though and whatever replaces it im sure will be used to poke at dick and ethan
