stfu

Shut the fuck up. It's simple. When you are annoyed with someone who won't stop ranting on instant messaging, you type "stfu!!" But be sure to limit yourslef to two exclamation points, though, because three will look too angry. You could also type two exclamation points and then a "1". Like this: stfu!!1. This way, the third exclamation point is there, but only in spirit. This puts a little extra anger, but not so enough to make the other person angry at you. :)
~On instant messaging~

"Stop Trolling For Unicorns": a phrase coined by youtuber wickedshrapnel from his "This gun f-ing sucks" videos. This was originally made as a response to when he would make a tgfs video on a gun that someone thinks the opposite way about the gun and would decide to post an annoying comment on how the gun does NOT suck.

stfu

It is a mysterious abbreviation that is apparently very offensive because everytime you ask they'll tell you to shut the fuck up. So it is essential to avoid asking for the meaning of the abbreviation.
