Well lets see. @clivingston005 nickname growing up was Loco. It originated in my freshman high school algebra class. My buddy was Adam Ramos sat next to me and some people decided that his name was Rico Ramos I was Loco Livingston. Mine stuck. I have had the nickname for 25 years now am still referred by this name by everyone from my high school. I have an alter-ego that appears when I am drinking (which I don't do as much any more) called "The Wildebeest". This person tends to play inappropriate songs on the jukebox at the bar. Nothing like playing "Roots Bloody Roots" in a country bar.
I am sure there is more embarrassing things to speak of, but I I will have think about it.
