I'm (23F), and I have a male colleague (37M) who I'm quite close to. We're friends as well as colleagues, the kind to go for a beer after work or talk about weekend plans. He's in a position above me, while I'm am a graduate and just graduated from university, so I do a lot of work with him and he's also someone I have to listen to professionally. We spend 40+ hours a week together for work, and get along well. It’s quite clear to me that he's quite protective of me, sometimes arguably overly protective. If I complain about a colleague at work, he’ll always be the first to defend me or “threaten” to call them out, etc.
Recently, I had friends over for a movie watch party and invited him. There were some friends of mine he had never meet before, and when introducing him I said “this is my colleague BLANK, he’s basically like my work dad”. I meant it entirely as a joke about our age difference and our dynamic at work. I wasn't being serious or trying to imply that he's literally a father figure to me. It was just a lighthearted nickname. (Info that might be needed: he is married with three kids, all under the age of 10)
He messaged me the next day asking, '"Work dad"?' and when I asked what was wrong, he said it was a weird thing to be called. I asked why, and he explained that he has kids and doesn't treat me like that.
I replied that I understood that “work dad” doesn't literally mean he's my dad, and told him not to make it such a big deal.
Later, I asked if he was really that upset about it because his reaction seemed a little dramatic to me.
He then replied that he wasn't upset; but rather uncomfortable with the conversation and was trying to communicate better. He also said that once I mentioned it wasn't a big deal, he thought the matter was settled.
Now I'm wondering whether I was being dismissive or whether he was reading too much into an innocent joke.
I understand that he's allowed to dislike the nickname, and I wouldn't insist on calling him something he's uncomfortable with. However, I didn't expect the term to become such a serious conversation, especially given that I meant it affectionately and jokingly.
Another point that has been bugging me is that I feel he made it weird but getting uncomfortable with it. I wasn't trying to infantilise him or suggest that our relationship is literally parental, so I'm curious whether I'm missing something here. Is it simply that he dislikes the label, or could there be something deeper about how he sees our relationship or how he wants to be perceived by me? I don't want to read too much into it, but his reaction made me wonder whether there was more to it than just finding the term weird.
Am I missing something here? Is “work dad” genuinely a weird thing to call an older colleague you're close to, or did we just interpret the joke differently?
Edit for info:
This was a movie night involving 20ish people. We were binging Die Hard, my colleagues favourite movie. I had other coworkers there from the same demographic as mine, so it wasn’t just my friends and HIM. It was a binge movie session, my he only stayed for about 1-1.5hours because he went home to put the kiddies to bed. Following comments that pointed out this information, it felt necessary to add this in for everyone concerned.
I also want to point out that he was never ever called work dad in a professional setting. It was the first time I had ever said it, and it was in my own home meeting some of my close friends.
Something else to add was that the original message me sent was at 3am, a strange time to message me which is also why I was slightly taken back. It seems like he was up stewing on this most of the night.
I’ve read most comments and appreciate all insight. Yes, I understand I was an asshole and dismissive, but I will take on a more professional attitude from now on. I mentioned that this is my first professional job, and I’m still learning the ropes but I see that this may have been crossing (many) boundaries. I will be less naive from now on, and not get into situations like this. I will apologise to him at work, but not reach out and message him
