YT=YouTube
　　When words are not enough to express what you want to say, then mentioning YT to anyone will give them the prompt　to open YouTube and search for a video that you may be referring on the tweet. Just do not forget to include a link at least so that they would have an idea on what is being discussed。
　　在Twitter上要写字数太多马上就要写不下的时候，你写YT就是让人家打开YoutTube去找你说的视频啦。千万别忘了附上你所说的视频地址哦。
　　BTW=by the way 顺便提一下
　　This is the perfect line for making an immediate change of topic or subject without being too pushy。
　　这是个换话题的好方式，而且还不会显得太突兀。
　　TMI=Too Much Information 信息量太大
　　Since Twitter has only 140 characters. However, there are a few people that could share so much details in so small of a space. Information overload in social networking sites actually happen when the individual finds it hard to stop disclosing details, even if there is no need to have it shared to others。
　　Twitter只能发140个字。但是有的人会在一条消息内摆出太多无关紧要的细节内容。有人会经常会忍不住要往发言框里塞内容，即使这些内容是完全无关紧要的。
　　FB=Facebook
　　Yes, Facebook. Oftentimes, being online on both platforms is considered cool and groovy by other users。
　　没错，FB就是Facebook的意思。其实Twitter和Facebook一起玩也是很酷很时髦的。
　　BRB=Be Right Back 马上回来
　　This is applicable for those people who are busy or setting aside time for something so important like getting to the bathroom, or eating some chow, etc。
　　这句话适合大家在忙洗澡、吃东西之类人生大事的时候使用。
　　LMAO=Laughing My Ass Off 笑翻了

　　在网络世界，LMAO或者LMBO的意思就是某人发现一段笑话、视频或者什么超搞笑的消息，好笑得让他都没法好好的坐在电脑前。
　　LOL=Laugh out Loud 大笑
　　A standard way of showing appreciation for a silly idea, or a funny joke, laugh out loud can be see both as an acronym and an emoticon with a double smile, or with the term LOL. On Twitter, it is used as a way of laughing hard。
　　当你在网络上发现什么雷人创意或者很搞笑的笑话，大家就会把大笑(laugh out loud)的首字母拼出LOL来，表示自己笑得不行了。
　　RT=Retweet转发
　　Being used as one of the best ways to expand the number of people reading the next couple of messages from other people, retweeting is a courteous way of sharing details that had been taken from another source. 转发是传播微博内容的最好方式，就是将微博消息和他人分享。
