An expression used when something is not done properly.

Originally derived from a small child eating a panini sideways (as opposed to starting at the end), and being told that it was not, in fact, the correct way to eat it.
*Person does something wrong / sings out of tune / {insert strange action of your choice}*

You: Now that's NOT the way you eat a panini.
