This type of thing exists, there's even a saying for it in swedish - "grabbig stämning" (loosely translated: "frat-house feeling"). But the last time I remember someone behaving like this was when I was just starting university, at around 19-20 yo, and even then that was just stuff between guys, never to a girl. We are very conscious of how we talk in sweden, and nobody would drop a comment vaguely similar to the ones mentioned above, unless they really hate their job and want to get fired.
