Glazed Bagel
The act of ejaculating on a woman's behind as she lies on her stomach, then rubbing the ejaculate across her butt cheeks with the tip of your penis. The end result being that her butt cheeks are covered in a glaze which depending on nationality may in fact resemble a glazed plain bagel.
As Julie lie on the bed near the window, John stood in awe as the glazed bagel he had just given Julie was twinkling in the moonlight ever so beautifully.
