The first name of NBA player Dikembe Mutombo. Possibly the best shot blocker in the 90's/early 00's.

Spoken whenever someone is flat out denied and followed with a finger wag, whether it be getting a shot blocked or getting turned down by a friend for a beer. For added effect, the speaking of the word should be grunted with a frown.
