Explanation:

[STC001654] When meeting for the first time, some individuals shake hands, while others give each other a cheek kiss, and still others still stick out their tongue. This last greeting happens in Tibet, and there’s a good reason for it: Lang Darma, a 9th-century king remembered as one of the cruelest leaders in Tibetan history, had a black tongue. Because many Tibetans believe in reincarnation, they began sticking out their tongues when meeting new people to assure them that they were not Lang Darma reborn. Over the years, the gesture has changed, and some Tibetans now use it to express agreement or even respect.
