The skin around a woman's or men's nipple that is a different color than the person's skin tone. Areola51 specifically refers to the abnormally large or otherwise irregular and disgusting areolas.
I was about to run train on that skank from last night but before getting into the deed I noticed she had some areola51 going on and couldn't help but barf.
