What the PHONK is this? (RFI, C/D, S&D)

My son Theo (nearly 11) makes youtube shorts (currently sports cars, previously fifa mobile clips) and soundtracks them with music called "Phonk" - in fact all the shots he watches seem to be soundtracked with this music, and while it sounds extremely fucked the videos have massive amounts of views. I am not sure how to describe it or whether I have anything good to say about it, but it's certainly a thing to start a thread about.

Here are the first two examples that came up.

Yeah I can hear that, also chopped & screwed, some dubstep, lots of the tracks also seem to be remixes of Spanish language music which I know nothing about.

Hey hip-hop nerds. What kind-of hip-hop is this?
