George Dalaras who was giving a Dafni was pelted with tangerines and bottles of water. (source newsit)
But there is nothing like variety of thick yogurt from sheep mil to get that real stained effect. Oranges, tangerines and bottles of water can be consumed, eggs and tomatoes are slippery so if you have an urge to shoot remember to carry ammunition...
Oh... and please remember to only use and endorse Greek products!
Greeks are not keen with “food fighting” but a knack of throwing things at people they do not like. And they throw anything and everything imaginable. From , to tangerines and from eggs and various vegetables to good old fashioned yogurt, when Greek people get mad then watch out... or at least duck! This act is called “yaourtoma” and the act of “yogurt(ing) someone” means to hit someone (usually in the face) with a yogurt. When citizens commit “yaourtoma” it is usually to show their dissatisfaction against a public figure, such as a politician, a singer, or the media. Obviously many call it inappropriate but "we are a difficult people" as Kissinger said and "difficult to tame". On such a note, EVangelos Venizelos should not be surprised in a "dairy delight" today since he is one of the least liked politicians in Greece.
