An endearing term, stemming from the word "uncle", that describes an older male friend, mentor, counselor, guardian, or paternal-figure, whom demonstrates unconditional love and concern for the well-being of teenage knuckleheads and delinquent thugs. Originates in the Juvenile Detention System, San Francisco, California.
1) "Unk says NO."
2) You best listen up and keep it real, cause Unk gone tell you to HANDLE YO BIZNASS and get right with yo'self.
3) He always talk smack about your streetname and flirt with yo mama - but we love him cause he's Unk.
