Pulled a Nigel

So you are hanging out with friends watching a movie. One friend, Nigel, says, "I have to go home, see you later."
Everyone says bye while still watching the movie.
20 minutes later you hear the toilet flush and everyone looks around trying to figure out who flushed the toilet.
Nigel was back into the room and says goodbye again.

So Pulling a Nigel is telling everyone you are leaving and then sedesecrating the toilet without telling anyone on your way out.
Bonus points if you literally live across the street.

We were all surprised when Dave Pulled a Nigel and stamp up the bathroom before leaving
