A frump is the top of your butt/lower back that is often visable when you bend over. Not as extreme as plumbers crack frumps are mostly seen due to low rise jeans.
Your frump is showing again.

The word that can be used in any way, shape, or form to describe general awesomeness. a lifestyle that's code is understood by all those who follow it, without explanation. It is everything yet nothing can compare to it. it simply is, and always will be, frump.
