You do know that "Seeman" is a proper name, right? And not spelled at all the same as the word you thought it was? I get a lot of proper names when I look at it--I've had "Harrison" and "Carlitos," I wonder if they're pulling their words from newspapers rather than a dictionary.
It seems a bit like my old cell phone, it would come up with the strangest words to suggest when I used the predictive text--finally someone told me that usually companies that program pull the first section of several major newspapers, so they have really strange words in them sometimes.
I should also point out that *neither* of those words was blocked them because *neither* of them is obscene. Although of course the combination would naturally make your minds go there.
