What does Brown Curtsy mean?

Brown Curtsy meaning in Urban Dictionary

The curtsy/bow one does instantly when walking into a men's room to check to see if anybody is within the bathroom stalls by getting a view of these legs. It's typically carried out in one fluid motion after opening the door so that you can enable a swift unbroken exit in a marine-like pivot should the stalls be occupied.To the untrained observer and anybody unexpectedly walking towards you (often from urinals) it looks as if you might be bowing into the stalls to demonstrate value.
