look up any word, like eiffel tower:
A creature that stalks you in the night waiting for when ur not looking and snatches your grundle. This creature is 3 ft tall, purple, hairy, makes a sound similar to "GIHEE", and can reach the speed of 47 miles per hour.
God Damnit, that grundle troll stole my grundle. Now i have to shit on my balls because my grundle has been stolen.

Grundle- The area between your asshole and your balls.
