Back beauty
A girl who viewed from behind looks stunning but when viewed from the front resembles a horse.
I was standing in a queue the other day and I saw this girl from behind and she looked absoutely beautiful but when she turned around I realised she was a back beauty.

Back Lot Beauty
This describes the vehicles that sit in the back of the car dealership. These are the used cars that are more difficult to sell.
