1. Someone whose work is primarily to do with filing, filling in, or reviewing paperwork; a bureaucrat. Sometimes hyphenated. I just got sick of being a paper pusher, so I quit my job and moved to Thailand to surf and teach English. I know being married to a paper pusher can't be terribly exciting, but at least she's got a stable, well-paying job, right?

2. A bureaucrat, especially one who adheres inflexibly to the details of the bureaucracy or administrative procedure. Sometimes hyphenated. He's just a paper pusher—he can't get anything changed about the way the government collects your taxes. Ugh. I've got some paper-pusher looking over my case at the moment, and she's being so anal about over little detail!

3. dated One who writes bad or dishonored checks, especially out of habit or as a criminal profession. Sometimes hyphenated. Apparently there's been a paper pusher passing through the state, depositing bad checks on Fridays and then skipping town before the banks are open on Monday. He was a paper-pusher for a while back in college. Nothing too serious, mostly just did it to pay for groceries or school supplies when he was low on cash.
