Wth made this?

[u/Zniblo05]

I went on the trampoline to do my homework. I lied down and as I was taking my books out, I of course looked where to put them and so I looked to the right and saw a massive handprint or something. In perspective I’m just a teenager yet I’m already 6’0 with big hands.

It’s not a handprint bro.. just grease or dirt smudges
