A friend went to Rum tasting at a cocktail bar called Highball Express in Canberra, and this was one of the offerings.
I note that Dan Murphy has it listed.
I think is looks like the Guyanian equivalent to Baileys Irish Cream.
As for rum making people angry - that seems to me to be more to do with the characteristics of people who drink rum, than the rum itself.
As some would know, I am quite partial to a drop of rum, but have never got angry on it!
