1. *If in Class or work*
Get up in blind anger (Knocking down your chair is a must), Flip your desk (if chair is attached, step out of said desk and do it from the side), and yell it out with ferocity, "FUCK THIS SHIT". Can also be done from saying it -> Getting up -> Flipping desk
2. *If playing a game*
In anger, as hard as you can, throw your controller at the wall or nearest solid object and proceed to yell. Make sure "Fuck this shit" is included.
3. *Scared, but cool manner*
Play off fear or even get into the feeling of your words, Turn to the side a bit, hide your fear and say, "Oh no, Fuck that shit"
Blind anger, yet again is a key factor, then click the X butto--actually fuck that shit. Manual shutdown the fucking computer and walk away. Fuck turning off the monitor.
