When you get done with sex and realize someone has left "chocolate" or "doodoo" on the pillow, just like a housekeeper at a hotel.
"Man, my girl pulled The Housekeeperlast night when she used my pillow to put under her ass during sex."
"Did you Donkey Punch her?"
"Not this time..."
A reference to the Nazi zombies game in the Call of Duty franchise. It is a derogatory term that highlights the game's focus on rebuilding barriers, running away form the zombies, and generally doing anything except kill zombies.
Bob: "Have you really been playing Nazi housekeeping for 6 hours straight?"
Rob: "You just don't understand the strategy man"
Bob: "get a life... or at least play regular call of duty"
