To perform a critical analysis of an event , in real time, with poor accuracy or judgment (or "judgEment" if you are British). Refusal to discuss or deliberate on the issue afterward is a common complementary course taken. Thought to have originated with FIFA referee Koman Coulibaly serving a "phantom" foul to the United States in the 2010 FIFA World Cup during a group stage match against Slovenia.
Koman Coulibaly definitely just coulibalied that "decision." The US threw rock and Slovenia threw scissors. Only a coulibaly could miss that; US wins.

To disallow a game-winning goal by calling a foul where none occurred.
Coulibaly became a household name in the US after Mali referee Koman Coulibaly disallowed Maurice Edu's game-winning goal in the 86th minute of the US-Slovenia match in the 2010 FIFA World Cup.
