The worst is when you see an (pushing) elderly woman with pigtails acting like she's 12. There's usually one of them in every liberal arts elective college class.
I was honestly waiting for the point where she drops the routine and explains what the problem is when gamers will only "accept" girls who behave like 12-year-olds. As the seconds left dwindled too low to have such a message this video made me kind of sad.
