My mom used to call me "Little Sh*t", then I got bigger so little was replaced with Big.
I have been labeled "Toad" (derived from Todd) many times.
In the Corps I had the handle "Texas" given to me, when I transfered to North Carolina I took 30 days leave time and grew a absolutley obnoxious moustache, way out of regulation size by Marine standards. Upon checking into my new unit I received the label of "Walrus" due to the size of my moustache.
When I was a drinking man "Mr. Obnoxious" was my nickname, tequilla tends to make you feel ten feet tall and bullet-proof.
My nickname as of late is "Dad", probably the coolest nickname of all. 🙂
