It's a training session for the rest of the year. A chance for people who do bad most of the year to change themselves. The idea is that you should be a better person going through and coming out of Ramadan. Sadly, that's not the case for everyone because they don't know it's purpose so they just blindly do it because their parents tell them to.
Lol. Those who do that don't get the purpose. It's sad that some people in this thread are objectifying women as sex symbols when it has nothing to do with the topic at all..
Of course. Lots of people do it because they are religious and lots do it just out of tradition and growing up doing it.
