You asked, but then gave three inaccurate statements that have already had detailed answers about the meaning. It isn't mansplaining because you weren't directing it at a woman, but the comment as a whole would fit the definition if it was directed at a woman.

Can someone mansplain mansplaining to me? It seems like any time someone with a beard inhales sharply.

Kind of like how manspreading is men sitting down.

And the male gaze is men looking at things.

All three terms are more nuanced than that even if some people ignore the context and use them in a sexist way against men in general. There will always be a number of people who use words incorrectly.
