A unit used when measuring time, deceivingly longer than an actual minute. Used to trick people into believing something will end shortly (ie. a minute) in order to get you to complete a task, yet often takes 2-3 times longer.

Bruce: About two more Taylor Swift songs.
Sean: More like a Rosie minute then.
