The mistake couples make when a partner sticks his penis or a lesbian uses a dildo or her fingers to penetrate the anus of a woman and then proceeds to stick the same appendage into the woman's vagina. They fail to realize that the woman's vagina will be contaminated with germs from the anus.

Get the Back of the steel drumsmug. a term used when we hit the ball against the wall. Afterward, it rebounds into the back of the opposing defensive player and ends up in the opponent's goal. This move is rarely seen in professional matches due to the high skills required for execution but can be highly effective against well-organized defenses. The element of surprise and special techniques are employed to catch the opponent off guard.
