Chilled coconuts like this are often sold on the streets by itinerant vendors in summer for people to drink the coconut water they contain.
This type isn't particularly meaty. The vendor will drill a hole in the shell and supply a paper or plastic straw. Very refreshing in the tropical heat.
Today, I picked up this from the supermarket. They (or some supplier) have not only drilled a hole but fitted a tap so you can carry it home without fear of spillage. They have also supplied a straw which the tap is cunningly designed to hold.
Then they have wrapped it nicely in a life-affirming wrapper. The large writing reads 加油 (jiā yóu), which literally means 'add oil', but is used as encouragement at sports events and the like to urge on your favourites.
They claim it's Thai, but I'm not sure I believe them. Maybe. However, there is no Thai on the packaging other than Young Ham Nom Coconut, Nam Hom being the transliteration of the incorrect Thai name* of the type of coconut, but they also grow in Hainan, China. Apart from that there is only Chinese and English.
* The Thai name is หนุ่มมะพร้าวหอม which transliterates as 'Nom maphrao hom'.
