The person in your life who will not leave you alone and/or wants to be like you. One who clings like a monkey and is always on your jock. This includes but is not limited to the following behavior: dressing like you, acting like you, using your patented clever phrases (like "jockmonkey"), remembering past events in a way that makes it seem you are actually copying off of them.
My jockmonkey got an eagle tattoo on his forearm a year after I got a swallow tattoo on mine.
