Pubic Tumble Weed 

Is general caused from neglect and faliure to properly clean either the bathroom floor, bath tub, or sink thus causing the hair to mangel together forming a pubic tumble weed

When I open the door to Eli's bathroom the waft of air generated from the door cause the pubic tumble weeds to dance frantically among the floor.

There where so many pubic tumble weeds in my grandmothers bathroom floor she made a wing from them.

When you haven't cleaned your bathroom in so long that if there is a slight breeze pubic hair rolls across your floor.

It's so gross in my bathroom that there's pubic hair tumbleweed.
