look up any word, like fleek:
(verb) To explain a simple fact, in even simpler terms, to a really thick person. This is often to degrade a person and to boost your social status by making you seem more clever than the idiot you just humbled.
A posh way of "telling someone" i.e. "he got humbled" posh version of "he got told."
I just humbled you in this definition. But since you are thick, I am going to humble you again and give you a simpler definition.

Guy 1: What's this random paper we got ages ago?
Guy 2: Let me humble you. That paper is our task for the exam that we will be sitting later today. The fact that you don't even know what the paper is about, proves you are going to inevitably fail this test.
