So I felt the same way about it; I'm a card-carrying nerd but most of my friends are decidedly non-geeks who still enjoy board game nights. At first, it started off with me being afraid of introducing them to the less mainstream boardgames. But one night I pitched Settlers of Catan (not exactly underground but also not Monopoly by any stretch) and surprisingly they took to it. And as we started playing more and more esoteric board games (some of them even having faux tabletop/RPG elements to them) I was continually surprised that everyone continued to enjoy them. The most surprising thing to me, though, is that eventually they approached me about trying out D&D. It was something I'd wanted to do for a while but had never communicated it to them because I just assumed they wouldn't be interested. Point being: You may be surprised. You have nothing to lose by suggesting it to them other than them saying "no". The 5th edition starter set even has the option of using pregenerated characters to reduce the friction. Maybe even start by showing them one of the CelibriDnD videos on YouTube; there's one with Vin Diesel and one with Terry Crews, not people who the general public usually think of as geeky.
