A moment in life you must tell everyone about V.I.A. Twitter. Usually told from a mobile device using Sms text messaging or a Twitter application. Sometimes involving a @ to another twitterer.
Girl-Oh my gosh did Taylor Swift just look at me?
Guy-No she looked at me! This is such a Twitter moment!
When something happens or someone says something that is so epic, that you absolutely MUST tweet it on twitter.
