When you are singing, humming, mouthing, or whistling a notoriously famous song, and some guy, be it a friend or someone you don'
t know at all, starts singing the words to the famous song with you timidly and awkwardly, making you stop singing immediately. Typically the theory of "pulling a
Jimmy" can be tested by walking towards the person in question, and singing "we are the champions." If the person joins you a couple words in, he is deemed to be pulling a
Jimmy. **Warning** avoid singing around these
people once you have caught on to them! Or better yet.... try and see how many times in a row you can get the fool to join you in singing gayly and then tell all of your
friends!
Dude, I went downstairs and started singing "Doe, a deer, a female deer," and this guy named
Jimmy started singing with me and I stopped immediately because it was extremely gay. He seriously pulled a
Jimmy there.
