I have flown behind you before. Definitely a anal nozzle move.

Plug the effin' headset back in if you unplug it. It REALLY is that simple to respect your fellow pilots who have to scoot the seat back and stand up to reconnect the airplane headset after the CA calls for push. You disconnected it, YOU should put it back. Leave the cockpit as you found it, or better. Anything less is uncivilized.
