Slang term used to refer to a person that has a strong back and strong legs from carrying around the weight of their massive genitals because they have the courage to go against the grain when necessary. This person is willing to do the dirty work to get the job done when all the other pansies are too scared to enter the realm of greatness. This person will work hard, party harder, and live life to the fullest; because that is the blacksheep way.
That blacksheep did an upperdecker in Kevin's mom's toilet. Nobody has had the guts to do that since 1997!
