The QE tactic

Really simple to be honest. When you are playing rainbow six siege you often press Q and E like a nudist trying to find his mother. The moment you press the shooting button you are dead. After the 0.3 second period of you not knowing what the fuck just happened you are going to rage so badly you are going to attempt to blow a bomb in Uzbekistan.

Guy 1:So did you do the QE tactic?
Guy 2: Yes!
Guy 1: How was the trip to Uzbekistan?
Guy 2: Groundbreaking
