this is Colombian slang for friend, buddy, bro. Conversely, it does not mean 'nigga' as was suggested by other definitions. The term is widely used throughout the country. Coining the term to signify 'nigga' is far to narrow a definition that ostensibly ostracizes 99% of the people that use it. The word is not used for just dark skinned people.
Qui hubo parce, que haces?- What's up man, what are you doing?
