You don't understand what it's all about! There's a lot of parody and mimicry of Thai culture, for instance, how they play the song loudly and dance on the tour bus (those dance moves around 0:36 to 1:00 are the most commonly used dance moves among Thai people who don't know many moves and tons of joke was made about so it's kind of our inside joke) The long-haired girl (Baitoey) is known by her overly exposed dressing habits and the song is a bit of parody of her and her song as well
