Your ass is the blackest 

This is said when talking with another person in a competitive manner, you concede that the other person has won.
It is usually said during one-up-manship contest.
Somewhat of a backwards "you win",but you really are the loser.
This is a very old saying...said as early as the 1800's.

Rhonda: I have a really bad headache.
Rick: Oh yeah, well I have a hangnail!
Rhonda: Yeah , and my knee hurts too.
Rick: Well, I guess "your ass is the blackest."
