Should I DM him?

I became social media friends with his mom after staying at her Airbnb. We connected there as she knew my parents and was friends with them when they were all younger. Her son is my age. She posts family photos, etc on instagram occasionally and a couple years ago I seen that he moved to my city and I while I didn’t pay much attention at the time, I have lately, and noticed from her stories and posts he seems like a great guy and I’d love to get to know him if he’s single. So I thought maybe slide into his dms but I also don’t want to seem like a creep. I don’t follow him on any social media.
I’m fit and active and have a pretty face but I’m not sure if he might find it weird. I’ve always just let men come to me so I’m curious how guys would feel about getting a dm from a stranger you don’t know at all but who somewhat knows your mom and obviously watches her stories? And if I were to slide in his DMs, I’m not sure what to say?
