The most insidious thing about the buzzwords managers use, as far as I can tell, is the fact that you absorb those words into your vocabulary without even realizing it. You spend so much time hearing 'weasel words' that before you know it, you're using those words yourself. It seems natural up until you realize what you're saying. You learn it through osmosis and you can even start using that speaking style outside of work and potentially embarrass yourself.
Just by prolonged exposure, you might end up incorporating parts of the corporate speaking style into how you regularly talk.
