Manukka:

Something one says at the brink of a climatic moment; This word means Man-you-fucking-nigger (or any form of nigger, nigga nigglet, etc.)

Can also be used loving, and for fun.
i.e. You are playing Call of Duty World at War, but get killed, so your character says Manukka before death.

Deuces Manukka.
