o-ring

1.
performed when a girl, especially a bitch, is sucking on your balls; the man, or receiver of the nut-sucking, proceeds to smack the bitch across the face quite hard. But, it is a failed o-ring if the cock smackage does not cause the bitch's, or the balls sucker's, ears to ring. The most effective o-rings will knock a bitch out cold.
2.
