Gwarn = Jamaican slang for go on! It is the message that Pato Banton brings to the world in song.
Pato gives an easy and inspiring explanation, he explains that, as a child, his mother would open the door and say “gwarn” (go on), leaving him to make his own way to school, “for those of you who don’t have someone holding your hand through this life, telling you exactly what you need to be doing, don’t fret, gwarn and do it!”
