When you've been partying hard and had very little sleep and you know you have to go out and do it all again the next evening, so you have a quick nap before hitting the booze again. So called because of the 24/7 party scene in Berlin which leaves very little time for sleep.
"Man, I feel like shit - I think I'm gonna have to have a Berlin power-nap before I go out again tonight"
