STFU, (shut the fuck up), is a word commonly used in texting and online chatting systems. It is to tell a person to be quiet and don't talk because your tired of them.
Although Kevin is usually funny, he made a very bad and offensive joke, and his friends told him to STFU.

Get the Alright bitch stfumug. What people that act as if some certain person's death *cough* Technoblade *cough* is the end of the world need to do. I mean sure, his death was a sad occurrence, but it still doesn't change the fact that it's stupid to claim that it's the end of the world, which a bunch of crybabies on YouTube and other websites like that are doing and will continue to do.
