I remember seeing tons of videos like 10+ years ago where it'd just be some guy ranting aimlessly into a microphone while Counter Strike or Calladuty footage played in the background. At first I thought they were captures from streams or something until I realized that no, they're literally just playing their voice over a completely unrelated video game to make it seem more interesting.

It quickly became a litmus test for people whose opinions are very boring and unnecessary.
