backtractive 

adj. referring to a person who is attractive from behind. Sometimes a backtractive girl is backtastic, but more often than not she is a butterface.

Walking down the street, you see what appears to be a hot girl with a fine ass infront of you. If she turns around and has a beard...then she is only backtractive.
