What is the most "bronze" saying you can recall from playing League?

Been playing league of legends since season 2. In season 5 I peaked diamond elo and from then I struggled to get higher so I stopped playing ranked games and slowly began falling in mmr meeting all sorts of players and experiencing different mindsets. So my question to you is what's the most obvious saying that indicates certain player being "mentally" stuck in bronze?
"No skin, no skill"
Feel free to elaborate
