I've used my name for various things in the past, mostly on forums but also online games as my avatar username. Not only that, I have registered 'croubie industries' as a business and used it when I subcontracted myself out for various engineering jobs (in a sort of "Vandalay Industries" way, if you don't know what that is then you're too young. Go rent some Seinfeld DVDs).
But the truth of where it came from? Me and a mate, back in high school (so at least 12-14 years ago), were around at his place late one night sampling some 'herbs' that he'd grown in his garden. We started just babbling crap, made up words that sounded cool, and I particularly liked the sound of 'croubie', we even tried to get it to catch on as a slang word for the herbs, it caught on with a few friends (particularly good when discussing nefarious activities around people we shouldn't, like parents).
Then I got a subcontracting job and needed a business name. Well, I didn't need one, but using my actual name sounded less 'business-like', so I made up 'croubie industries' as a sort of 'vandalay industries', but also having a dig at my bosses (who didn't know my other made-up meaning for the words).
13 years later and it's still around, even if it doesn't have the herbal double-meaning anymore (we all grew out of it, as most kids do).
Meanwhile, the global-octopus of croubie industries has stretched into many areas: photography & accessories, hifi/pa/guitar speakers and amps, computers & parts, and I can't think of what else. It's amazing what you can get when you ring up suppliers and say you're from a business (rather than some poor uni student), trade prices and free samples and all the rest.
