When a fat sweaty man with a handlebar mustache beats you in a one on one game of basketball or a game of 21, oftentimes for a cash wager. He usually wins through aggressive use of the post game and emphasis on fundamentals. This is the highest form of basketball humiliation, worse than having your ankles broken or even being posterized
The burly man lowered his shoulder into my chest, and his sweaty mullet splashed into my face. With his handlebars glistening in the sun as he drained the winning bucket on a surprisingly agile fadeaway, I knew I had just played a game of mustacheketball.
We've all been there.
