Some rats that have probably broken in to your house and ate most of your food, or you could call the person closest to you a fat rat just because your bored.

Not really noticed, kinda like a "hey, I'm just here" They usually do the most out of anybody, but nobody really notices them (Senpai, notice me!), so they just stay back there and act useless, like Hinata. That's right, Sakura is more useful than Hinata. If you disagree with me, Have you ever watched Naruto Shippuden?
