Well it really has 2: Wood Booger & Sgt. Ruby. Wood Booger was the original - I like Bigfoot lore and ran across some place where they are called Wood Boogers. Plus it’s Sarge Green so Booger. Sgt. Ruby came from a friend of mine that has called the JL that since I bought it. It also goes by Money Pit and Garage Ornament according to my wife.
Finally decided on one, and it holds a double meaning. My '71 Jeepster Commando that I sold last year was named 'Beast', decided to go with 'SOB' as in the Son of Beast, for my JLU. It can also be called the son of someone else when it costs me money.
