To absent oneself or leave early from school or work when one would normally be required to be there. Primarily heard in US. I was so restless and bored at work that I decided to play hooky after lunch. Hey, Jim and I are playing hooky from school on Friday, do you want to come with us? That's the last time you play hooky, mister! From now on, I'm dropping you off at school every morning!
