Shame!
From New Zealand. Mock any embarrassing situation with the word “shaaaaaaame”, following by a stroking of the chin between thumb and forefinger.
Regional variations; “Shamola!”, where you rub the forefingers of either hand together, and oddly enough, in Wellington, of saying “TAAAAAAAAY!” and pulling a lower eyelid down.
(Shame in England can be accompanied by licking the finger and holding it to the shamed person's face. The heat of their embarrassment will cause the spit to "sizzle". Well, it won't, of course - that's why you have to shout "sizzle".

1) Find unpopular/poor/ginger kid and approach him, smiling in unthreatening manner.
2) Ask victim to tell a joke; watch his face light up at this unexpected act of social acceptance.
3) No matter how funny the punchline, DO NOT LAUGH, instead remain silent, look him in eye and hold chin in hand in quizzical manner.
4) Wait until victim shows signs of confusion or discomfort, then begin pointing at him and chanting: "Shame! Shame! Shame!"
5) Watch as crowd gathers, all pointing and shouting "SHAME! SHAME! SHAME!"; becoming a seething mob, creating a bayying and increasingly hysterical VORTEX of shame, until victim cries and/or pisses pants.
