I know you wanted just BPs...but I'll include my cornsnakes as well because some of them have some interesting/nerdy stories behind them.

Starting off with my BPs:
Fluffy (normal) - I acutally rescued her. There was a girl who stopped her neighbor from letting her go in the front yard. That girl then gave her to me because she didn't like snakes, but she didn't want it thrown outside in the summer heat to die. When she gave her to me, she asked if I could keep her name Fluffy and I said I would. Now, I wouldn't even dream of naming her anything else.

Charlotte (spider) - Everyone needs a spider ball python named Charlotte from the movie Charlotte's Web.

Jax (lesser) - no reason. It just popped into my head on the way home from the ETHS Expo


And now for the cornsnakes:
Severus (snow motley) - Everyone needs a 'Severus Snake' Sadly, my Severus turned into a girl one day....

Anuna (bloodred) - I write on RPGs (don't ask) and one of my friend's characters is named Anuna.

Travis - I bought him from Travis Whisler and labeled his cup "Travis" so I could remember who I purchased him from. While I was talking to Sam from BHB at the NARBC in Arlington, she asked if I had named him Travis. Since then...it stuck.

Callie - She's a Miami Corn and my buddy is a HUGE fan of CSI: Miami so he asked me to name the snake Calleigh (not sure of the original spelling) after the hot actress. So, I obliged and changed the spelling.

FNU - I bought her in August at the NARBC and never really named her. So, I've been calling her FNU (pronounced fa-nuu) which stands for "First Name Unknown"
