It's not sick and vile used in this context. Hump is a real noun, used as an alternative for speed bumps, or any mound. Check any dictionary, I'm sure it'll have it.

I drove my car over the hump. i then got out and preceeded to walk over the hump again and again and again. I then laid down all over that nice hump, and started to spoon the hump. I continued to spoon the hump, until my "pipe bomb" exploded.

(Yeah, thats really natural...)

tough crowd

stop humping around!
