Someone who eavesdrops (usually in an office setting) and uses the information gathered to their advantage, often to the detriment of others.
My co-worker Bruce feels totally threatened by me. He listens in when I'm on the phone with my man and he told our boss that I was making personal calls at work. That ear hustler wants my job! He even told our supervisor that I'm planning to call in sick tomorrow.
