That's the point of the gif. He isn't saying it's hard to hold. He is making an exaggeration of the "complaints" that people have about the DS3. In reality they don't know how to properly hold it.
It's the pointy things down there that are useless for people with hands larger then childrens to hold on to. I mostly just hold the dual shock with the fingers, with the 360 I hold on with the whole hands. Much more comfortable.
