i got in a fight with my sister over the pronunciation of it and she said duhkyne and i said daykyne. im not sure what it is but i think it is dahkeene
They used to write it on stuff as two seperate words like Da Kine. with this in mind i am 100% certaine that is how you pronounce it. My little brother insists on daykine though and it pisses me off to the max.
both Wade Simmons and Thomas Vanderham called it "duh-kyne" during a conversation i had with them a couple years ago. i'd say they would know how to pronounce their own sponsor's name.
