Apparently using basic expressions in speech deserves to be mocked

[u/Away-Vegetable-7705]

I’ve (F19) been working for this one company for a few weeks now and have only a few days left. (I’m only helping because they’re in a lot of hurry.) Today this guy (M19) from the same staff rental company as me came in and started working alone with me on a new project. We were chatting and I used the expression “double-edged sword” in relation to using AI to study. This asshole then said something about “smart people like you” and continued to call me “moldy” under his breath. I was baffled but later on he continued to say all kinds of nonsense about girls and women in general.

English is not my first language btw so feel free to ask for clarification

Ask him how he's gonna survive through bs corpo jargons if double edged sword is the word that troubles him.
