Woot! The online expression of enthusiasm, and other words formed by technology, is now in the dictionary.

According to the Associated Press,  the 400 additions in the 12th edition of the Concise Oxford English Dictionary, published this month, also include retweet, which is to repost another Twitter user’s message.

Cyberbullying, a form of online abuse, and textspeak, the abbreviated language used in cell phone messages, are also now part of the 42,000 entries.

Sexting, the act of sending explicit photos or messages by mobile phone, was also added.

Less high-tech new entries include jeggings, a jeans-leggings hybrid, and mankini, a sling-style bathing suit made infamous by comic character Borat, according to the AP.

Editor Angus Stevenson said the new additions “are just carrying on the tradition of a dictionary that has always sought to be progressive and up to date.”
