Well, my last name is a long Italian name. When my husband and I were teens, they used to call him Chaf for short on the football field. (pronounced CH like choo choo, short A like half) I always thought it sounded so cool. So .....I STOLE IT! LOL Chaffy evolved from there from my good online friends and so it stuck.
A note: I used to also have another name KMAmom...for my three kids, Kristi, Michael and Anthony. People kept asking my why I was so angry....and I didn't know what in the world they were talking about. UNTIL, I found out that KMA is an acronym for Kiss My @ss !!! OOPS!!!
I don't use THAT name anymore. LOL
