You acting like we haven't seen him speak in other interviews in recent years. He is not talking like that.
The point I'm trying to make is that the people who raised him spoke that language, grammar, and intonation.
His Mother, and extended family, and neighbors. In the country he was born, and among older generation in the section of Brooklyn he was raised in.
He likely communicated with Mom, relatives, and elders in the same language and speech.
Outside the house, he learned and communicated in the language and speech of the environment.
Back in Belize, he communicates in the original language & speech of his parents' culture.
The Shaggy and Shyne comments sounds like dudes think these guys dropped out of the sky as teens in America, and that speaking in the language/speech of their parents is an act.
