look up any word, like blumpkin:
 
1.
A mythical creature with the stature of around 7 feet tall. They wear a pair of wings which span around 5 feet wide. They are very commonly mistaken for a condor or bird of that variety. They are the cousins of the Sasquatch, and live in upstate New York, but can be seen anywhere up to Deerfield, Massachusetts. A Berkowitz is very rare, and can barely be photographed because of the fact that it is too tall for each photo.

Tommy likes to give himself a berkowitz before he goes out.
