Losing My Mind

I spent a good three minutes looking at a completely new word the other day. It was at the end of a marketing text, and I couldn't for the life of me figure out what it meant. Ретвитните (retvitnitye). The root was a mysterious "tvit." The prefix means to do the "tvit" again. The suffix means that it's an imperative.

And then it dawned on me - "tvit" means "tweet!" The text is asking you to retweet an announcement (on Twitter). A Yandex search turned up lots of ретвитните, плз (retvitnite, plz), which means "retweet this, please."
