reason for saying/asking 什么叫活腻歪了 (what does tired of living mean) in tv series 敢死队：第11集
This part of the conversation doesn't sound natural to me. A rhetorical question like 什么叫xyz is only used after the other person labeled him xyz. Without a previous line like 你是活腻歪了吧, the usage seems out of the blue and ambiguous. After watching the video, I think what happened is there is something along that line in the original script but got edited out from the final version.
A conversation like this should go:

A: 你小子是活腻歪了吧？也不看这什么地方，就敢往里闯。
B: 什么叫活腻歪了，我是来找人的。

Translation:

A: Are you courting death? Look at this place, do you think you can barge your way in?
B: What do you mean by courting death? I am simply looking for someone.
