Get the nm, i should have stfumug. 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.
