“Woot,” “sexting” and “cyberbullying” are now in the Oxford English Dictionary (Caleb Jones/AP)

Retweet, sexting and cyberbullying have all made the cut to be included in the venerable volume, as have textspeak and woot.

So now it’s completely OED-sanctioned to say, “Woot! Many people have retweeted my message warning about sexting and cyberbullying...though they’ve had to use textspeak to make it fit in 140 characters.”

(Note: That was way harder than I thought it would be.)

Here’s a rundown of the official definitions:

- Cyberbullying (noun): The use of electronic communication to bully a person, typically by sending messages of an intimidating or threatening nature: children may be reluctant to admit to being the victims of cyberbullying

- Woot (exclamation, informal): Used to express elation, enthusiasm, or triumph: I definitely get Fridays off, woot!

- Retweet (verb): (On the social networking service Twitter) repost or forward (a message posted by another user): tweet the URL of your posting: people love to retweet job ads. Also: (noun) a reposted or forwarded message on Twitter: traffic spiked quickly and contained a mix of retweets and original posts

- Sexting (noun, informal):The sending of sexually explicit photographs or messages via mobile phone: like it or not, sexting is part of growing up in 2010

- Textspeak (noun): Language regarded as characteristic of text messages, consisting of abbreviations, acronyms, initials, emoticons, etc.
