People are offending fellow commuters by manspreading, revelling in bants with their friends at beer o'clock and having a brain fart while talking about the Grexit - but it's all NBD.
Those are just some of the 1000 new words added to OxfordDictionaries.com in its latest quarterly update, which reveals trends in the use of language.
New entries include "manspreading", when a man sits with his legs wide apart on public transport, encroaching on other seats, "bants" for banter and "NBD", an abbreviation of "no big deal".
"Beer o'clock" and "wine o'clock", describing the appropriate time of day to start drinking the beverages, and "brain fart", a temporary lapse or failure to reason correctly, have also been added to the online dictionary.
"Hangry", an adjective used to show feelings of anger or irritability as a result of hunger, also appears.
Topical news terms have soared in popular usage.
"Grexit" and "Brexit", referring to the possible departure of Greece and Britain from the European Union, and "deradicalisation", the action of causing a person with extreme views to adopt more moderate ones, are also included in the update.
Other additions include "bruh", describing a male friend, and "pocket dial", meaning to accidentally call someone while your phone is in a pocket.
New words, senses and phrases are added to OxfordDictionaries.com once editors have gathered enough independent evidence from a range of sources to be confident that they have widespread currency.
But they do not get into the Oxford English Dictionary unless continued historical use can be shown.
Oxford Dictionaries senior editor Fiona McPherson said the addition of slang words was not a dumbing down of English, but showed "creative" use of language.
