overshare: The name given to TMI — too much information. As a noun, it refers to content on the plethora of overly personal blogs and social networking sites that share personal information of interest only to the person posting, as well as to other inadvertently or intentionally revealed online and offline personal information that nobody really wants to know. Overshare is also a verb describing the act of TMI-transmission.
Overshare might lead to readers/listeners exclaiming such phrases as, "Stop whining and buy some toilet paper!," "Nobody wants to hear about your penis!", and "They really let you take it home with you after the surgery?!" Honestly — unless you're a doctor or speaking to one, there's really no reason to bring up the details of any -ectomies, -otomies, or excretions.
Overshare was chosen as Webster's New World Dictionary's word of the year. Click the preceding link to see the blog where people were asked to vote for WOTY among five candidates: leisure sickness, cyberchondriac, selective ignorance, youthanasia, and of course overshare. You'll also find a nice little video about how and why overshare was chosen.
