Cover art for You Would Know lyrics by Queens of the Stone Age

Not every song is about drugs...

This song (in my opinion) is about a relationship, which is dissolving.

"you would know" is kind of a spiteful malicious post-relationship remark

At the beginning he's a happy robot (this may be a reference to Josh's "robot rock" style), happy in the relationship. They're similar, or cut from the same cloth, but their relationship is too explosive/not working, or ripping at the seams.

The rest of it seems to be just the relationship falling apart and he puts an end to it; cutting (the cloth), crosshairs in the eyes.
