Comes from the combination of the two words Slore and Orca. Slore is defined as being a combination of both the term slut and whore to identify a rather loose female. Orca is the term used in identifying the breed of killer whales. The combination of the terms result in a word that describes a fat whore who will do anything for dick.
"Damn, Keri is a such a slorca."
