when a man and woman are laying in bed post-coitus and the woman is still very wet. She reaches down to touch her vagina and rubs her juices on her partner's upper lip. Most commonly done to signify that the woman did not reach climax and thus is not satisfied with her partner's performance.
Did you hear that Lindsey gave Chris a really wet senorita after she didnt come for the second time that day! Damn, he needs to get that shit under control!!
