Skibidi Toilet is 100% worth calling out - very in line with that DIY weird vibe of the Newgrounds/AlbinoBlackSheep era. Has to have been Garry's Mod or probably these days, Source Filmmaker (SFM).

Makes me feel old, though - that's a meme from my kids generation, which I know about only because of them.

I think it is source filmmaker.

My nephew and everyone in his generation seem to be really into it, even to the extent that I heard kids singing 'tears for fears' songs (from the 80s) used in it in the street the other day.

I tried to show him source filmmaker in an attempt to get him to be interested in messing around / producing stuff rather than consuming it on an iPad, but sadly he wasn't interested.

There's a YouTube channel called BuiltByGamers that does nothing but post absurd fake podcast clips where two guys pretend to argue about FNAF and Skibidi Toilet and get all the lore wrong. I think it's interesting because I've never thought of trolling elementary schoolers as a business idea. Watching them feels like getting a lobotomy though.

That reminds me, tangentially, of the videos with deepfaked voices of Obama, Trump, and Biden playing video games together. For me it gets stale fast, but I will admit there's something pretty hilarious about the whole setup.
