My Nicknames and where they come from:
Am, Ams, Am Jam and AJ - all started from family, basically just an abbreviation of my name Amber Janae, I even dropped Lee when I got married so I could still officially be Am Jam and AJ. AJ is one of my favorite, because if you call me that you truly are someone that is close to me.
Ambular - this started freshman year of college by some of my besties, we're not sure why they started calling me this, but it is from Clueless. I think we just thought it was funny and it stuck, 10 years later they are still calling me that :)
