Macternity leave
When people get a new Mac and pretend they're on leave just to play with it all day.
I got a new Mac and told my boss I was on 'macternity leave' so I could mess around with it all day.
My coworker took a day off just to try to use his new Mac. He didn't even know what it did.
I got a new tablet and took two days off just to figure out how to use it. My boss called it 'macternity leave.'
