My mom called my boyfriend ‘random’ and I’m upset about it?

I’ve been with my boyfriend for 3 months. We were talking about taking a trip abroad , as my dad lives abroad and has a house there. I was speaking about it to my mom today and she said she doesn’t think my dad would like it that I would bring a ‘random’ guy there. I know we haven’t been together long but I felt this was unnecessary. Should I let it slip?
