Unc 

Unc or Uncle (the brother of your mother or father)

Your old Uncle who still thinks he is still young and fresh. The type of Uncle to say "Back in my day" or "What do you know about the fundamentals?" while wearing creased red and white Jordan 1 shoes.

Uncle: All of these younglings trying to dunk the basketball like Michael Jordan. Dunking only gets you one point, let me show you the fundamentals.

*he pumps fakes the ball then shoots, making sure to hit the backboard first"

You: Ok Unc! That is pretty good!
