marty mcFly it

To sleep in one's clothes, as done by the character Marty McFly in the movie "Back to the Future". Also known as "Michael J. Fox it".

I'm too tired to change into my pajamas. I'm just going to Marty McFly it.

I'll lose my sleepiness if I change into my pajamas. I'm just gonna have to Marty MacFly it.
