look up any word, like blumpkin:
 
1.
A man who shaves small animals and fires the fucking thing up his ass using a tube of some sort. The animals can be any of the following: gerbils, mice, hamsters, rats (either sewer or store boughten), beavers, muskrats, small dogs, large dogs or pretty much any other animal you can think of shaving.
Look at the way that guy is standing near the waterfalls. I would bet hes a serious gerbiler.
