I remember noticing in China that it seemed very common in Chinese casual chitchat, but to Western ears it sounded inappropriate. In the context of a lecture, I imagine it would come down to whether the delivery seemed genuinely part of the point or an excuse to push boundaries. Hard to gauge without audio/tone. I can’t think of why you’d report this unless you had a serious issue with the lecturer or they were being purposefully inappropriate.
