Not being there is hard to give opinion but sounds like he was trying to make a harmless joke and may have come off wrong. Don't forget, COVID has set some people's social skills back quite a bit lol. It's not uncommon for people to try and strike an overly specific conversation to fit in with the scene. I would have chuckled and told him it was a factory lightweight part.

I made the mistake once of letting autocorrect call my Barracuda a GranD Coupe...after the backlash I do it on purpose now because watching some people lose their minds over something so trivial entertains others.
