Idk how to describe it accurately, but it's like gorecore but with the inclusion other biological stuff and an overall unsanitary look

I mostly see this sort of aesthetic with media that's deliberately made to be gross.

If i could give examples of things associated with this aesthetic. i'd say the webcomic Awful Hospital, Invader Zim, and for music maybe songs with heartbeats?

Maybe i'm just describing body horror, and i'm just seeing body horror that doesn't have the stuff i listed

Another one is like 'elemental' as in the context of Fire, water, earth, air etc
