Gross nasty food or meat

Same meaning as ok. It is a more masculine version of the variation of ok known as oki.

This is a type of person that believes that he is not clapped , he is surprisingly a black af igbo guy and can sometimes be mistaken for a bullet but this mistake can easily be mistaken as he's head is way harder than a bullet

i conclusion if someone calls you an oku then you know that you are fucking ugly
