STFURNSMF 

A way to tell someone to stop talking with so many words in so little space. When someone continues with obsessive ranting you reply with stfurnsmf. (Shut the fuck up right now stupid mother fucker)

Johny wouldn't stop talking about his lame communist politics so I told him to stfurnsmf.
