What's weird about it? I'm not disputing that it might be fun for vibe coders. Just that they seem to really like using that particular word.

I love coding and it is fun for me. Vibe coding on the other hand - not fun at all. It feels to me like playing slots.

But then again, I never liked gambling.

When your only defense is “I’m just having fun!!!!” after dumping your toxic waste in the net, it’s not a weird take.

Not weird at all. It's a common motte & bailey tactic, when your defence of the utility of something fails you can just say you do it for fun!!!!!!!.
