1. See "sexy" in a real
dictionary.
2. "Sexy" for idiots that can't spell, or think that corrupting the English language makes them "mod" or "hip" or "alternative" or "
crunk" or "swell" or "bitchin" or whatever the
hell the kids are saying these days. This concept is also evidenced by the gradual substitution of "z" for "s" in plural noun forms.
