Picked up this recipe from Mr. Boston Drinks. But I cannot find the history behind the name. Sounds very Thai origin. I think Ko Adang is the bigger island next to the Ko Lipe island in Thailand that has the famous Pattaya beach.

Very tropical is its ingredients, this has two kind of rums – Anejo rum and Coconut rum along with lime juice, mango juice, coconut water and ginger liqueur.
