Specifically in Greece and in Cyprus, the single nod of the head up that indicates "no" is almost always combined with a simultaneous raise of the eyebrows and most commonly also with a slight (or complete) rolling up of the eyes. There is also a sound that sometimes accompanies the whole gesture, called "τσου". This sound bears heavy resemblance, but is not identical, to the British tutting sound. The use of "τσου" is optional and reserved only for heavy emphasis on the "no".
