Humpmuffin 

Someone who is just a general dick/bitch. You call them this because they are so low down they would hump a food.

Josh, that kid is such a humpmuffin all he ever does is bitch and complain.

humgruffin

The act of using your lower lip as a shovel to clean smashed pie off the floor.

This is done without hands- to be properly humgruffin, you must rest your chin on the floor with your lip extended and propel yourself forward with your legs.

I dropped a pie last night, and before I could get the broom, Katie was humgruffin that shit up.
