Shut-the-fuck-up: a term used when a normal request for someone to be quiet seems to fall on deaf ears; may be used in either a normal or assertive tone of voice.
Honey, would you be terribly offended if I asked you to please STFU for five minutes?

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 This was originally made as a response to when he would make a tgfs video on a gun that someone thinks the opposite way about the gun and would decide to post an annoying comment on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.
youtuber1:" OMFG THE HK21 DOES NOT SUCK IT IS BEASTLY YOU'RE JUST A FAGGOT WHO CAN'T USE THE GUN!!!!"

youtuber2: "will you stfu, you must have no life."
