A very specific mental handicap used to describe millionaire athletes who seemingly forget how to play sports right in the middle of a game. The term was coined when the Cleveland Browns punt returner Poyer let a punted football bounce off his face on the 3 yard line. Clearly he was suffering from the Cleveland Browns Downs.
“Did you see that guy had his shirt on backwards?”
“Yeah and it was a button up too. What a dickwhistler.”
“He must be suffering from a case of the Cleveland Browns Downs.”
