I've read one poster's comments that "Cheeba" isn't a word. Of course it's a word. New words are added to our language every day, and "Cheeba" has been used for plenty enough years to establish itself as a "word". Consider the word, "bling". It hasn't been around nearly as long as the word "Cheeba".
I have seen other spell "Cheeba" as "Chiba". Well, "Chiba" is incorrect, too. Chiba is the name of some place in Japan and consequently the name of many Japanese restaurants and a name also given to a particular, fat sushi roll.
Some posters have used the word "Chiva" to describe Marijuana. That's also wrong. "Chiva" has meant "Heroin" for a very long time.
A "Cheeba Cohiba" is a blunt made by hollowing out a cigar and packing it with Cheeba (Marijuana). Cheeba Cohiba is named after the world-famous Cohiba Cuban cigars.
