The words are descriptive, i.e. red-haired and female. The numbers were needed as redbird on its own had already been taken. Doesn't take a genius to work out what the numbers signify, regretting it now!
Redbird if the 72 bit indicates your age? No I will not swap with you! If its the YOB then yes please
If its the total in your bank account definately NOT
