You could try the deliberate misspelling approach! Just replace S with Z and TH with D. Granted you sound like either a hip-hop star or a German officer from a WWII movie, but the kids are crazy about that kinda shit=)

A word of advice, you cannot replace S with Z if it is used in conjunction with another consonant, like 'sl' and 'st'. So you can say www.hotslutz.com, but not www.hotzlutz.com, then people think you're Polish

And yes, I have had entirely too much caffeine today :broccoli:
