It also sounds like 'to die' in Chinese.

'Si' (Pronounced Like The Si in 'Sir') in the four sense.
'Si' (Pronounced Like The Si in 'Sir?' The difference in pronumciation is the tone with this one going down in the middle and ending up like a question, and the Si in four just going down in tone like a statement.) in the death sense.

Here is a list of all the things Si can mean.

Numbers in Chinese often sound like words, here's a wikipedia entry on it.

Is it really so hard to see that the underlying issue is lowest common denominator pandering? It is always offensive to a very small group of people who don't fit the stereotype, neutral to a larger group, and actually enticing for most. Almost every woman who sees advertizing cares a little bit about at least one thing in the 'bag of woman stereotypes', which includes {hair, weight, decorating, fashion, children, food} just like almost every man cares a little bit about at least one of {cars, alcohol, women, jock-activities, gadgets, slapstick}.

Take everything in the bag, put it together, and you have a lowest common denominator stereotype. No reasonable person thinks that people are completely defined by everything in the stereotypes that apply to them, but when it comes to women marketers sure seem to.

It would be exactly as stupid for Dell to have a male-focused site, plastered with links to Maxim magazine and Playboy in the margins, that advertized laptops that come with Budweiser coupons and 'girl in bikini on muscle car' wallpaper. Some of you have observed that it is a growing trend to depict men a certain way in advertizing (as the stupid man stereotype). This isn't a sexist agenda at work, it's lcd pandering again.

The problem is: what if this kind of advertizing was the only kind that marketers used to target men? What if every advertiser who wanted to target 'Men' targeted the gender in the same way, whether they are advertizing snackfoods, PC vs Mac, or ax bodyspray?
Every 30 seconds would be beer commercial populated by smug fratboys.

The very small group who don't fit the stereotype would be increasingly more annoyed and shrill, the larger neutral group would see less and less of themselves as time goes on and become annoyed, and the Marching Morons group would continue unaffected.

This is what is happening with the relationship between women and advertizing. The advertisers are not showing as many archetypes for women as they show for men, and it has been going on for long enough so the neutral women are becoming annoyed, and the annoyed women are becoming shrill. This effect is coupled with an influence to try to spot sexism, so people are seeing the advertiser's pandering in terms of the effects that it has on continuing to stereotype groups of people being one-dimensional. But really, they are just trying to hit a note with as many people as possible to get the most out of their advertizing dollars.
