a-dawg: what?

Rewind the clock to senior year: advanced individual activities (aka: the senior p.e. class).  
We were playing badminton: K-Fed vs. Alexis.  I was struggling serving the birdie. After several failed attempts of tossing and attempting to hit the shuttlecock (hehe), K-Fed offered some words of encouragement:
"Come on A-Dawg"
I came to a complete halt.  I might have even dropped the birdie.  Looking K-Fed straight in the eyes I questioned:
"Did you just call me ADOLF?"
Through out the rest of the day he continued to call me that and started the list of the nicknames given to me by K-Fed.
