Stepping into an elevator at the parking garage where you last left your car, only to realize you have no idea what floor you left your car on, typically after a long shift at work when all you want to do is be at home.
Akeem: Dam, work was hell today, I can wait to get home, what floor you on?

Semmi: Four, no wait, six, aww shit, looks like I’m playing Parking Lot Roulette
