I saw this in GTA V and decided it was a good idea. When you over a link, the cursor turns into a hand showing the middle finger instead of the default index finger.
I took these cursors: https://www.xfce-look.org/p/1284345/ and changed the textures with the hand (changed the index finger to the middle finger and repainted)

Install: unzip to ~/.icons
