A silly, light hearted compliment used in jest. Easily substitute other colours as
appropriate for the situation.
Best used with people with a
sense of humour as opposed to those who take
everything seriously.
You walk in to a mainstream restaurant. The waiter tells you

You say with a smile, "Thank you. That's very Black of you."
Your boss gives you a raise, ditto.
You get a
birthday card with money in it, ditto.
Your sibling offers to finish your chores, ditto.
Etc.
