I had never heard of this before, thanks for sharing. Cambodians have a lot of special dishes associated with certain holidays and occasions, very similar. Funny that bami is a cassava patty to Jamaicans and it is noodles to Surinamers. "Mii" is noodles is Cambodian, a similar pronunciation.
Another funny thing @fruityfruitz might like, in Cambodian "nyam" means to eat, so that would be the first word Jamaicans already know in Cambodian.
