I'll try to explain to my readers who are not from Malaysia. The video is about a popular, young singer in Malaysia - Siti Nurhaliza. Think the equivalent of Britney Spears in America, if you will. Malaysia is currently rife with news about her as she is finally getting married (therefore breaking the hearts of millions of her young [and don't forget old, err "matured?"]) fans. The video is a song of disappointment.
The lyrics (thank you kindly DITH):
Datuk K, K, K,
Kau nak kawin dgn Siti,
Kau dah potong jln kami,
Ini tak boleh jadi,
Kau memang tak sedar diri.
Dulu Siti kata,
Dia tak kisah siapa laki,
Asalkan dia seornag yg baik hati,
Tapi Siti sekrang dah mungkir janji,
Nak kawin dgn Datuk, duda pulak tu lagi!
Siti Nurhaliza is getting married to a "Dato" which is a title for someone of high status or importance in Malaysia. Another translation for "Dato" is "Grandpa", which hints the age of the person she's marrying (which partly explains the reason why her fans are so upset!)
