"You're going down" is an expression that means that you are going to defeat someone. In this video, Gru says "you're going down" because he plans to discover and arrest El Macho. This phrase is usually said before a fight of some kind and is commonly used. Ex: You are going down! Ex: He's going down for the crimes that he committed.
