[Opinions] Re: Irie is a Jamaican slang word, I'm pretty sure...
Jamaica and Rastafarianism are intertwined. Irie is listed as a Rastafarian term on wiktionary and other sites.
I knew a girl named Irie and she pronounced it eye-REE which I think would be indistinguishable from EYE-ree in most conversation. I believe she had a caribbean background although I'm not sure if she was necessarily Jamaican.
