“Shut the fuck up”, used when really mad and someone is being an annoying asshole. Works better than anything else because if you yell this people will definitely listen to you, and maybe be scared.
Random annoying ass: h-hey did you watch the dream video???”🤓🤓🤓it was so sussy and chaotic I wear a mask with a smile for hours at a time
Normal person: SHUT THE FUCK UP BITCH!!!!!!NOBODY GIVES A SHIT. STFU YOU NASTY BITCH ASS DREAM STAN LOOKIN UGLY ASS.

This is a word that has a deep meaning behind it. If someone is annoying and loud you can use this word. I can’t guarantee that it will work cause there is some person called woeser always loud af and can’t stfu.

Stfu means SHUT THE FUCK UP, it is usually used when someone say something dumb as hell and they need to be told to shut the fuck up.
