A Kantos Minute
A time that's just long enough to make you forget why you were waiting in the first place. Like when you're waiting for your friend to come and they're taking forever.
'I'll be there in a Kantos Minute.', He arrived three hours later with a new haircut and no pants.
'You said you'd be here in a Kantos Minute.', He showed up with a bagel and a new problem.
'We'll be ready in a Kantos Minute.', They were still arguing about the bagel an hour later.
