Ascertain a word heard on TVB series? Sounds like Maan4 Bing2(?)

Scenario: Woman berating a man for not knowing who she is; she's a bit model who had appeared in commercials on TV. The man had also earlier insulted her, so she's understandably a little miffed with him.

She went something like: 你有冇睇過我廣告㗎？Then, addressing him directly, she called him Maan4 Bing2(?) meant as an insult and chased him away.

I figured Maan4 probably = 蠻，but have no idea of the Bing2(?), not even sure if the intonation is correct.

The video had no subtitles at all, not even Standard Chinese to help, so I could only play by ear. Any help is much appreciated! Thanks!

Edit to add: More context, the man not only insulted her but was an unscrupulous salesman who tried to sell her a lemon product too, so in that light, I think Maan4 could = 謾， which the dictionary says means "to deceive or hoodwink", which sounds fitting.

Still not sure about the bing2

Edit to add 2: Thinking further, could also be 盲 (maang4) something? Since the scenario is the woman berating the man for not knowing who she was, so she could be saying he was "blind" (i.e. ignorant)?

Edit to add 3: OK nevermind, figured it out, it's 盲炳。
