Don't kink shame me!

I thought the footage of a lion licking and gently rubbing a warthog before he casually carried it off in his mouth to eat it was the kinkiest thing I ever saw an animal do, until I saw a vision of a T-Rex trapped behind plexiglass at a "Jurassic World" style amusement park. This T-Rex eyed a visitor, made towards them, then smashed his head against several feet of thick glass, creating a huge thud sound. 

Then it proceeded to lick the glass in a splash of dinosaur saliva.

That did it. I'm done.
