Have you ever had a nickname and if so how did you get it?

Well, there was of course everything that rhymes with Vicky (sticky, icky, licky, etc) that Scott and Julie gave me. lol
Let's see, there was caboose, like the caboose of a train because of being the last kid. Uh, bumper for being the biggest and last, like a bumper crop. In fifth grade I got confused and thought that my nick name growing up was boomer, so when my teacher asked if there was a nickname we liked and wanted to go by, I gave her that name and for the rest of the year she called me Boomer.
My friends Lee and Alysa and I all liked Sailor Moon, we each had a favorite character; mine was Sailor Jupiter aka Lita, and I was very mothering, so they called me Mama Lita. That one has stuck.
