<human>: As it turns out, the idea for the "game" my friend and I played was given to me after being embarrassed by an upperclassmen my sophomore year. 

I was leaving my conditioning class with said upperclassmen, who I knew from playing sports, let's call him Jim. We're walking and shooting the shit on the way to our next class as usual when a rather attractive girl my age comes walking towards us in the opposite direction. I had a few classes with the girl and we were friends and had talked a few times. I really had no interest in her because she had a boyfriend from high school and there are plenty of other single girls on most campuses including this one. Anyway, as we pass by her, her and I exchange hellos. Jim waits for her to get about two paces away so it sounds like he is just talking to me, but knows she'll clearly be able to hear him and says, **"Isn't that the girl you're always talking about?!"** with a shit-eating grin on his face. I froze and had nothing to say. I felt that if I had tried to defend myself, I would have just sounded guilty so I remained speechless. 

After the crimson color had left my cheeks, it dawned on me that it was my duty to continue Jim's joke once he left the college. Fast forward to my senior year and my friend "Alex" and I are constantly using this on each other at bars/parties/etc. when we see each other talking to girls. It was a great way to make it awkward for whoever was talking to the girl, and resulted in some pretty funny moments. Probably not the most effective way to wing-man for a friend, but incredibly fun to do and watch play out. 

So reddit, does anyone else have special ways to mess with their friends?

Can you provide a brief overview of the text?
