<P> Gleeking may occur spontaneously due to accidental tongue pressure on the sublingual gland while talking, eating, yawning, or cleaning the teeth . Gleeking can also be induced, for instance, by pressing the underside of the tongue upwards against the palate, then pushing the tongue forward while simultaneously moving the jaw slightly forward; or by yawning deeply and pressing the tongue against the palate . Practice is usually required to induce gleeking consistently, and induction is more likely to be successful under conditions of salivary stimulation . </P> <P> In rural parts of North India, it was customary in olden days for mothers to lightly spit at their children (usually to the side of the children rather than directly at them) to imply a sense of disparagement and imperfection that protects them from evil eye (or nazar). Excessive admiration, even from well - meaning people, is believed to attract the evil eye, so this is believed to protect children from nazar that could be caused by their own mothers' "excessive" love of them . However, because of hygiene, transmission of disease and social taboos, this practice has waned and instead a black mark of kohl or kajal is put on the forehead or cheek of the child to ward off the evil eye . Adults use an amulet containing alum or chillies and worn on the body for this purpose . Sometimes, this is also done with brides and others by their loved ones to protect them from nazar . </P> <P> Shopkeepers in the region used to sometimes make a spitting gesture on the cash proceeds from the first sale of the day (called bohni), which is a custom believed to ward - off nazar from the business . </P> <P> Such a habit also existed in some Eastern European countries like Romania, and Moldova, although it is no longer widely practiced . People would gently spit in the face of younger people (often younger relatives such as grandchildren or nephews) they admire in order to avoid deochi, an involuntary curse on the individual being admired or "strangely looked upon", which is claimed to be the cause of bad fortune and sometimes malaise or various illnesses . In Greece, it is customary to "spit" three times after making a compliment to someone, the spitting is done to protect from the evil eye . This applies to all people, it is not just between mothers and children . The spitting is light and from a distance, so it is not actual spitting on the face etc. of the person--which if done is derogatory . (Nowadays, one is more likely to just say "ftou, ftou", an interjection imitating the sound of spitting .) This practice sometimes extended to spitting on living plants and animals so as to protect them from sudden death or diseases, and spells which were claimed to break the curse of the evil eye exist . </P>
