The sack-whack is a sexual maneuver which is preformed mid-coitus between two, consenting or non-consenting individuals, with at least one of them (the receiver) being a male. The initiator (male or female) sits astride their partner (male) while receiving anal or vaginal penetration. When the initiator feels his/her partner is on the cusp of climaxing they will perform a quick, albeit sharp, open or closed handed strike against their partner’s scrotum. If performed correctly, this act will undoubtedly stave off the male’s orgasm and allow for a lengthier period of sexual stimulation for the initiator.
Bill: What happened with you and Sandy last night?
Tyrone: I had to sneep that bitch after she gave me a sack-whack.
Bill: Yeah, and then what happened?
Tyrone: We both felt awful, so we had a make up sandish.
Bill: Awesome!
