Horrible. Makes me think of ''Frisco'' (not that I don't like San Francisco, in fact, it's one of the few havens of sanity left in the US, but I'm not big on the nickname) and Sisco (remember the r'n'b singer Sisqo? The Thong Song is one of the worst tracks ever!). It just sounds utterly unpleasant.
I could see this as a leader of a gang.
Good for a fanfic.
