bower-bird bed-buddy

A considerate dude who frequently/diligently tidies/smoothes/re-adjusts the blankets/pillows while canoodling in bed with you, just as the well-known feathered grass-walled-nest dweller does to please a female who drops in to visit.

Tiffany always appreciates my being a bower-bird bed-buddy, since it feels so much more pleasant to sleep with me if the blankets are always neat and uniformly covering us, especially during the cooler seasons.
