Do you fire up the e-cigarette if you're feeling a bit meh?
Or maybe - fuelled by FOMO - you leave the twitterati, throw on some jeggings or a skort and twerk on the dancefloor?
These are just some of the 500 new words added to the official Oxford English Dictionary.
For a word to qualify for a spot in the Oxford English Dictionary, it has to have been in popular use for at least 10 years in both novels and newspapers.
And, perhaps surprisingly, 'twerk' is the oldest of the new additions. Researchers found that the word - then spelled 'twirk - was first used as a noun in 1820, describing a "twisting or jerking movement" or "twitch".
The verb followed in 1848, and by 1901 the current spelling was in popular use.
Twerking - made popular by pop star Miley Cyrus - is defined in the dictionary as dancing "in a sexually provocative manner, using thrusting movements of the bottom and hips while in a low, squatting stance".
The dance style was born in the early 1990s New Orleans "bounce" music scene - but the team believes the origins are the same.
She said the new entries - which include photobomb, jeggings and crowdfund - had all "earned their place" in the history of the English language.
