 Get the Mud Flapmug.
Get the Mud Flapmug. Sagging butt cheeks with age and weight loss such that a pencil could be held in the crack between back upper thigh and bum. Vastly superior to all alternative definitions for the sheer ubiquity of the phenomena but also because legs are the human equivalent to wheels and human mud flaps are therefore perfect homologues to vehicular ones. Entered Urban lexicon in Spinal Tap's hit Big Bottom in which this second chorus appears:
Big bottom, Big bottom
Talk about mud flaps
My gal's got 'em.
Big bottom
Drive me out of my mind.
How can I leave this behind?
