I'm not sure what you call this goal celebration, exactly? The Congo goalkeeper, Muteba Kidiaba, does a new and strange sort of goal celebration in the African Cup of Nations when they faced off versus Ghana.
Perhaps it's the bunny hop or the mad butt dance or the my butt is being bitten by thousands of red ants and that's why I'm hopping on it. It's certainly hilarious, whatever you want to call it. Take a look.
