E-Time
It's when you promise someone you'll be there in two minutes, but then you're still there an hour later.
I told my wife I'd be home in ten minutes, but I was still at work at midnight.
I told my friend I'd be there in two minutes, and I still wasn't there by the time he left.
I told my coworker I'd be right there, and I was still at the coffee shop an hour later.
