"Wait huh .." or "strong yaa .."
For people who were his bad mood, this word could be heard very judgmental, as if you're talking to does not attempt to wait or weaken themselves. Likely he was tired of hearing these words from many people. So rather than impressed speaking without second thought or care about the feeling, don't say it.
