You were not the only person. It's like the bow and arrow, it was so obvious that it was invented simultaneously in multiple locations. Not saying I was the one but there was a person on another board that may have had it before you did.
fwiw - I did though coin Porkchop, I give half the credit to Jimmy go IU who asked what we should call him. And, yes, Painter was told what we call him. That made me smile.
But, that too may have been so obvious - considering Piggy, Hoghead Keady, the coeds who resemble pigs and the rancid smell of pig shit, boiler and desperation in WL - that something related to pigs was needed and multiple people came up with it.
