While having anal sex your partner cums/nuts/shoots his load into your ass then you immediately clench your ass cheeks together and jump up and down. After jumping a couple times you squat and release whatever comes out of your ass that has been mixed up with the semen into a cup for your partner to drink.
Friend: "Sarah, you gotta tell me how you night with Nick went?!?"
Sarah: "It was amazing, best yet! He pounded me in the back so good and when he came, I gave him a reverse milkshake."
Friend: "OMG, that sounds like a good night! Now you got me feeling thirsty."
