Shut the fuck up. Its simple. When you are annoyed with someone who wont 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.
