Googly
A leg spinner released from the back of the hand to spin the other way is called Googly. The grip is similar to that of a leg spin only the release is different.
Its Simple:
Do keep the wrist supple and make sure you finish the bowling arm towards your back thigh like you would with an in swinger. Most effective if pitched on driving length outside the off stump, encouraging a right-hander to drive against the spin
