There's all the manifestations of my name "Caro,Car,Liney, etc." and my last name (which no one can ever get right >>).
And manifestations of my username "Kick, Kickyy, Kicky, K, KT"
THEN there's the odd ones:
My brother called me Chuck Norris, because I when we got into a car accident, I managed to kick the smashed door open(while wearing flipflops, not steel-toed boots xD). And also because when it happened, the only time I cried was when they had to push my fractured bone back in place (Much more painful then it sounds, I swear. The knumbing injection didn't work well. NEVER FRACTURE YOUR BONES).
Some of my iscribble.net friends call me Jason Bourne, because I always manage to outsmart the rulebreakers.

My friend Jen calls me Hubby, and my friend Sara calls me Chumsy.
I'm called Athens by my friends Sara and Alica (who are Sparta and Persia, respectivly)
