a nickname for someone with a large penis, or a name for someone's large penis. First, the nickname was adopted as Big Penis, however over the years, it shrank to Big Cock. However the gangsta's and ho's decided that its still to long, so combining the two words Big and Cock resulted in BKOK
DAMN SON, that is a huge BKOK; when refering to a penis.
Yo BKOK, get your ass over here; when refering to a person.
