My dad, who is a troll, when I was small, used to tell me that KFC stood for 'Kaalee Phat Chut'. Because I was so young, I didn't actually know what it meant and Phat sounded like it started with an F. When I got older and learnt the language properly, I realised that it meant 'black ripped vagina' and I was absolutely mortified when I learnt that I believed that's what it meant for 8 years of my life.
Thanks a lot
