When you come across an interesting tweet and you want to help it spread - you retweet it.
There's usually a ReTweet button next to each Tweet, so you can usually just click that.
The syntax of a ReTweet is the abbreviation "RT" or the word "Retweet" followed by the username of the person who tweeted it (e.g @User) and then the content of the actual tweet.
You may also modify the original tweet to make it more interesting for your followers, or because the addition of RT + username makes it longer than the permitted 140 characters. In order to make everything fit, you may need to omit words or use shorter synonyms or abbreviations.
RT stands for "ReTweet" and is when one Twitter user copy pastes something another Twitter user has said b/c he/she found it interesting and for some reason wanted to repost it on their page.
rt = re tweet
