Why do teenage girls and young women use the word creepy so much?

According to them, everything is creepy. If you don't talk constantly about nothing, you're creepy. If you're sitting by yourself, you're creepy. Waiting for the bus by yourself, you're creepy. If you don't have an iPhone, you're creepy. Don't have a facebook? VERY creepy. If you're ugly, there's no doubt in the world that you're a dangerous creeper. Why is everything creepy to them? Do they genuinely find these insignificant things creepy or are they just trying to make themselves seem important?

A problem reagrding the battery of my iphone?

Actually my iPhone was functioning quite well till Yesterday as it ran out of battery and switched off. I charged it a bit (12%). Then, I unplugged it and made some phone calls. As I plugged it again, the sign for charging was not there. I also, connected it to my laptop. The laptop didn't recognize it. I then, used other cables and batteries. It didn't function. I switched it off and on several times, nothing changed. I just left my iPhone plugged. After something like an hour, it was charged for something like 10%. What the hell is wrong with it? I don't think that its battery life has ended. Cause I have it since something like 2 years. I appreciate any help!

Added (1). Thanks, but why doesn't my Laptop recongnize it so that I can backup my data?
