Oh man you've got this wrong. Your porn name is your first pet followed by the name of the road you lived in. Mine is Bambi Church, my sister is Misty Moat.
Without wanting to be a party pooper, many banks ask for mother's maiden names as a security check, so anyone who knows your NSC name now has an extra bit of information if they want to do some identity theft.
My mother in laws porn name has made me laugh, bare in mind she is very old, her first pets name is a very racist and derogatory word, ready......N***** Wilson.
