iScratch 

A result of using any iPod (with a metal back) or iPhone without a case, characterized by ungodly amounts of fine scratches on the back of said device.

John decided to blow all his money on AppleCare rather than get a case for his iPhone. Now because he went commando, his phone has a nasty case of iScratch.

Is that iScratch on your iPod, or did you just try to chisel your name on it with a screwdriver?

Do you anger me? I fierce, I scratch you! 

This is a meme that I recently started to see around a few sites, but has probably been around for a while.

I found that it's from the intro to a cat hentai game called "Neko Kawai Gari". Needless to say, this intro is very weird, and features what sounds like a young Japanese girl singing a song over pictures of hentai cat girls.

One of the lines in this song is "Do you anger me? I fierce, I scratch yooooou!"

You may praise a tail. You may touch my striped back. Do you anger me? I fierce, I scratch you! Nya Nya, she's a spectacled persian cat.
