Man, a silent hater is just one of those dudes who stop by your house and they are all like, sitting in a clawed armchair, sippin' on their drinky-drink and just straight up muggin'! I know you know what I'm talking about. They just use their silence as another way of imposing their superiority.
Dude, this brother has just been hating on our joint all night! He's a silent hater to the fullest.
