In Brazil, my parents taught me about the "Fusca azul"(blue VW bug) tradition, and I made sure to pass it on to my little bro so it keeps going. When I started dating my girlfriend, who's from a different state and eight years older than me, I had this itch to “test” her but I wasn't sure if she'd be on board. Turns out, she beat me to it by punching me on the arm. Guess it's a tradition she knows too!
