Mud Flaps

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?

Mud flaps

Noun
Matching tattoos located on the backside of the upper thigh on each leg, just below the buttocks. It is the basic stepdaughter of the tramp stamp, with a ribbon tied in a bow being the most common design.

"I thought she was real original until she turned around and I saw she had mud flaps."

Emergency flaps

The side fasteners on a babies diaper/pamper is used here as Emergency Flaps. If your emergency flaps are about to blow, have blown or are stretching thin, basically means all hells going to break loose for a freak out, meltdown, you name it. It's the last straw, you have lost control if they've blown. You still have sanity if they are still intact.

"Dude, if this lady doesn't drive faster than 2MPH my emergency flaps are going to give."

"My emergency flaps blew, I was so pissed I had to leave."
