I like to go all-in and ruin it for them.

It's only funny as a dogwhistle when they get the pavlovian response from their shitheel audience.

If you pretend that the joke is really funny and clever but especially original, and you ask where they came up with the idea for that joke it kills it for them because they are forced to confront the fact that they're rehashing a punchline without a joke that has been circulating for over a decade by this point.

They can't call you on it and say "Are you stupid? This joke is so old that you must have been in a coma if this is your first time hearing it." because then they're admitting that the best humour they can muster is a joke that is so tired that it's not even a joke anymore. [Insert Nietzsche quote about truth here]

Leaning into it kills the joke because it reveals the uncomfortable reality behind the joke that they don't want to acknowledge.

For extra points, if you are stuck in a small space with people like this, repeat the same joke over and over to run it into the ground and absolutely spoil it for them permanently, like a dad intentionally misusing terms like rizz so their kids will find it cringey and they'll immediately abandon using those words from that point on.

I don't do online games often at all, maybe with IRL friends once or twice a year, so I largely see that shit on social media.

My go to is: "shut up nerd"

"Wow, the west can't be saved" closes tab and go back to looking at pictures of Hunan mountains

This is why I always make sure the game has some way for me to directly punish them

Like in Destiny, I tell them I'm kicking them and then I do

I don't cotton that shit

I've yet to run into any chuds but that's because my online gaming is mostly done on private servers I try to vet before joining.

Low hanging fruit: “Lol,” “I don’t care,” etc.

Higher-order stuff I call out directly: “I know you don’t actually give a shit about [x y z],” “You’re trying to gaslight,” etc.

The only online games I play are FFXIV and the recently created hexbear minecraft server and this isn't a problem for me.

Wanna know how to find people that eat meat?

in video games: teamkilling. lots and lots of teamkilling.

voice chat was a mistake

Well chuds on a game have an obvious in: their gameplay. So ill check and unless theyre top k/d or dps or whatever that's my in. it's quicker to distract them by ignoring their bait and laying down some for others to pile on with too. If I get into paragraph battles everyone else is afraid to jump in so i like opening up a new vibe and setting out chances for people to use easy cliches like "cry moar"...theyll use em.

Straight up just tell them they're an uncomfortable person and offputting and disengage go the extent possible. Most people acting like that on the internet are seeking approval or validation from others and think those views and opinions are the way to get them. If they don't get the response they want, they'll change how they behave until they do.
