Laziness.

Took my FFXI name, added two syllables to the end, then broke it into two pieces. It turned into a format along the lines of:
Given(First) Name: [SomethingThatLooksLikeAName]
Family(Last) Name: [NounNoun] or through a different interpretation [AdjectiveNoun] (Japanese words; cynics would say to increase the weaboo factor)
