Which generation slangs do you find most irritating and senseless?

Each generation has a unique lingo. For me, I'm a Gen X. I'm already trying to figure out the slangs of Gen Zs, which by now, I've kind of accepted. After watching a video by The Smart Local on Gen Alpha lingo, I find myself feeling very disturbed. Where on earth did that generation form the slangs from?? Theirs is the most senseless.

As my title says, which generation lingo you dislike most?
