Mine came from a nickname I gave my husband. We worked together at a towing company when we started dating. We had a lengthy discussion about the stupid nicknames couples give to eachother and how we would never do that cause it's childish. Well of course being that smartass that I am I started calling him Pookeybear from that day on. The dispatcher at work heard me call him that one night and from there everybody started calling him that. I still remember them calling him into the office over the PA system "Pookeybear to dispatch please"...yeah, that went over well
