Oryx - I'd love to say something but I'm usually too busy trying not to hurl all over the place at the sound they make when the spit. Man, they're bringing up the real deep stuff, aren't they?!

Judging from the fact that it's only certain people who go round spitting it must be a cultural thing that's accepted in their society at home. Doesn't make it right, but that seems to be the case.
