Any of numerous varieties of (thankfully) rare areola mismatches, so visually jarring as to cause the finder an audible, Tourette's-like outburst.

"I took Betty Sue out last night. When we got home she wanted to have sexual relations. I had to decline because that bitch had some nasty ass scareolas."
