Coconut refers to a CP favorite, or more broadly, an obsession with same-sex love. This terrier comes from the Thai drama "Interpret my love with your heart", in which the main character in the drama started to hate the coconut smell, but because of inadvertently smelled the coconut scent on the hair of the other main character, began to be crazy obsessed with the coconut smell, so that means the love of the CP of this drama, or more broadly refers to the obsession with the love of the same sex.

Also cursing coconut is a detrimental word with a sarcastic mocking meaning. It probably means that the person is simple minded, smelly and hard character, not good at changing, and even worse to get along with.
