Jacobism

1. the combining of two idioms, which has the effect of confusing the audience, rather than clarifying the intention.
2. the incorrect application of a single idiom, which leaves the audience mystified.

Examples of a Jacobism are:
1. We'll "pull it out of the ball park". "Do you mean, 'Pull if out of the bag' or 'Hit it out of the ball-park'?"
2. We're "barking up the wrong track". "So are we 'on the wrong track' and 'barking up the wrong tree'?"
3. We'll need "a three eyes check". "You mean a four eyes check?"
4. We need to "get our ducks on a plane". "So we need to get our ducks in a row? Why do they need to be on a plane?"
