I Boo when there is traffic, I boo at work (in front of my boss) I boo when someone walking down the street looks like a hot mess, I boo my friends, I boo my kids! It's gotten so bad that I booed the McDonalds drive-thru guy yesterday when he told me "they didn't do cash back"
(I embarrassed my kids)
It's probably annoying, but I just can't help it!
What's your overly used expression?
