It goes something like this: You’re having a candid discussion about your boss over happy-hour drinks and someone comes up with a sidesplitting nickname for her. (OK, it’s “The Incredible Sulk.”) But instead of texting it to your sister, you send it to--dun, dun, dun--the Sulk herself.

Whether you need to un-send an email or change an Instagram caption (damn you, autocorrect), head over to the slideshow with a notebook in hand. Your reputation is counting on it.
