I thought the point you were making (amongst others) was querying the mass use of the word tits by women. I assure you American women use it just as much as anyone else. Just because it's taboo for you doesn't mean it is for everyone. In the great scheme of things it's not a terrible word. While we're at it; this is a global board so I find it offensive that anyone who isn't American is treated like a second class citizen.
Sorry for skipping a few hundred posts. I'm just reading through this post and wanted to add that a while ago I notified on someone calling some one else a spastic. Now I found this truly offence given it was from a High School teacher as well. The person I notified on wasn't given an infraction for what ever because, and this shows the double standards of some posters about using the word tits is because: The poster in question is American and it means something else over here.
So yeah, I'm with Deckerd on this. If Americans can "get away" with calling someone a spastic, I'm sure saying tits up should be perfectly fine as well.
