backspiration

Sweat from the back region, particularly the small of the back, that turns your shirt game upside down. Grey t-shirts are particular harbingers of backspiration. The hotter and more humid it is, the bigger the backspiration stain. Sigh.

“Oh man, sometimes I hate walking around the city in the summer. It’s like backspiration central.”

Backstep

To go back on one's word or actions. To break a promise or change one's mind, usually with little or no prior notice. To renege.

I called to confirm with Cheryl if we were still on for our lunch date, but she decided to backstep on me after I made the reservations.

back ass road

A road that is not simply a back road, but one that is so deep into the middle of nowhere that it deserves the word "ass" in between.

"Where you at?" "I dunno, some back ass road I can't believe I have service."

The fine art of slipping a thumb in the anus.
