Just spent the weekend with ten of my daughter's friends, all 9 or 10. All I heard from them all day yesterday was 'that's so preppy', 'you're so preppy' or 'heyyyy preppies'. Seriously wanted to rip my ears off after a while.. what does it even mean and why do they say it all the time. Leads me to my question. What is the most annoying phrase/word your kids have picked up?
