I realized this is the funniest thing I hear all day. I hear it atleast once a week from someone. I also can't help but let out an massive roll of my eyes when someone does say it.
Now these people DO exist. I know atleast two, but I think it's hysterical how every single average person manages to come up with this idea that they're this fantastically intelligent person that just does not apply themselves. They never have anything to back their claims up either. No scores that are significantly seperated from the average, almost never a decent GPA, and most of the time they emanate stupidity.
