Ha,Ta'd
To be Ha Ta'd is when you say you'll just do something for a little while and then you're stuck in a time loop with no escape.
I said I'd just do one level of the game. Now it's 3 AM and I'm still trying to beat it.
I decided to watch one movie. Now it's 2 AM and I'm still eating popcorn.
I said I'd just fold one sock. Now it's 1 AM and I have a mountain of laundry.
