This entire phrase is a hyperbolic expression used to emphasise the idea of "**how badly** someone does something", correct?

Its grammatical construction eludes me, though; I'm not sure how to parse the phrase -- how these separate words get to have the figurative meaning as a whole.

```
из рук = (getting) out of hand?

вон = out there?

плохо = badly

```

Also: What other verbs than "разбираться" are commonly coupled with this expression?
