This is when a woman proceeds to perform oral sex on a man. The man then ejaculates on the woman (the part of the woman to be ejaculated on is up to the man getting the BJ). After the man cums he then proceeds to spread open the woman's meat curtains and gives her a round of applause by gently smacking her vagina. Screaming ENCORE is optional.
My girlfriend gave me head yesterday, it was so good I demanded the Encore.
