Well I highly doubt what I had is any sort of common word and it wasn't part of my username. I mean part of it was a name, and doing a quick wolfram alpha search, is not common at all. I'll play around with it and see if I can get anything to work.
If you absolutely must have a certain word in the password and it's complaining about it being common, you can increase the length of the password until it gets accepted. For example, if the password "common123" was rejected, you could try "common12345678" instead. Also, it's not only common words but common names as well.
