What about PBuford? I think the name needs a hidden reference to the pig with out saying pig. That way only the knowing will get it.What about one of the following:
We call it buford, after it's resemblance to the cars Jackie Gleason drove trying to catch bandit/cledus? Then, it can be buick powered with a 9" rear and have a double meaning as a buford?
Or you call it smokey? Same thought process.
If you want it to be like your "child" you can call it junior. Pays homage to both pig and to buford's son.
OK, so I could go on about that train of thought for much too long. I'll stop for now.
