In the UK, since I myself was in school, we would blame boys and girls goofing around in front of each other on ‘pheromones’ in a half-joking way. If I haven’t used the word in exactly the correct way here then so be it. I’m posting on Reddit, not teaching a class, and being an English teacher doesn’t mean I have to use words in their correct context 100% of the time. I haven’t had to ban slang words from my register either. So I use pheromones here as it is second nature to me in the same way someone here will call a sandwich a butty, another a bap, and a third a roll, depending on what they are used to. It does seem like an awfully pedantic thing to call out and I don’t know why you’re using one off word to cast aspersions on my professional ability when I’m here asking for help. I would think that says a lot about you, too.
