Alligator Blood 

In poker, the ability to turn on your friends or do anything within the rules to win when the time comes. From Doyle Brunson's 'Super System' book.

'...one of the best friends I've ever had...but when I play cards with him, I do my level best to cut his throat and he tries to cut mine. In the trade, this characteristic is called Alligator Blood.'
