To be the worst ref in the world in your respective sport. Coined after a horrendous job in the 2-2 tie between the United States and Slovenia in the World Cup, which included a "hand" ball off the neck, constant bad foul calls, and a goal taken away with under five minutes left.

Get the Koman Coulibalymug. The world's worst referee. He decided he hates Americans so screwed us out of three points, on a horrible call. He didn't even make a call. He just blew a whistle. While, four US players were being held by the Slovenians. Great call dumb ass.

Get the Koman Coulibalymug. The worst referee in FIFA history. Can also be used synonymously with eunuch, blind man, and royal douchebag.
