Circle Game, The
The game made famous in TV’s 'Malcolm in the Middle', but an old favourite.
Object of the game is to get the victim to "see" the magic circle, made from your thumb and index finger (in the classic "OK" sign). The magic circle is only "active" when the victim looks directly at it when it is held below waist level.

The victim’s attention is drawn to the magic circle using diversion techniques such as pointing out untied shoelaces, dropping coins etc, anything where one must look below waist level. The magic circle can then be introduced into the victim’s field of vision. When the victim looks directly at the magic circle, you are permitted to punch them on the arm for their gullibility. A pain in the arse to explain, breathtakingly simple in practice.

Also known as The Orifice. An additional rule is that if you managed to get your finger in and out of The Orifice before it closed, you could punch the other guy on the arm 3 times. However, you had to rub it better otherwise you got punched back.
The Orifice also works in photographs; I made one in our department's annual photo, and am technically entitled to punch everyone in the building.

If the intended victim can insert their finger into the circle without looking at it, the effects are reversed, allowing the victim to punch the aggressor.

Perfecting this technique will stand you in good stead come the end of term school disco, during a slow dance with Amanda Byrne or any other tart in a too-short skirt.

If the victim inserts his finger into your circle in an attempt to reverse your win, you can close your fist and trap his finger, which grants you double reversies. Punch his arm twice as hard to let him know that you will not tolerate such insolence.
