With terms like mahoosive and al desko, the editors of OxfordDictionaries.com say they've made the largest quarterly update in their history, adding definitions for 1,000 words.
We'll clarify that while the digital service is affiliated with Oxford University, it's officially separate from the venerable dictionary.
The new additions range from pop culture ("xlnt" and "permadeath") to business-speak ("algorithmic trading").
"One of the benefits of our unique language-monitoring program is that it enables us to track in detail how English language evolves over relatively short periods of time," Oxford Dictionaries Editorial Director Judy Pearsall says. "For instance, in this age of the selfie, perhaps it's no surprise that average monthly usage of the term 'duck face' is 35 percent higher in 2014 than it was last year."
Here's a selected list of the new terms that the editors shared with us. We'll publish it here so you can celebrate your cultural currency — or shake your head at the whippersnappers who think they're all that:
