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.
