What does it mean?

My girlfriend (Northern Irish) and I (Portuguese) were talking earlier today and we were talking about our types and looks, and she said that I looked like I was from Larne - is this an insult or a compliment?

Edit: thanks everyone for the barrel of laughs you’ve provided in the last 24 hours. My girlfriend and I joke around with each other a lot and have thick skin so no harm done. I’ll still be lawyering up just in case! Big up my Larne brothers with 12 fingers and toes 🫡
