Are you offending by manspreading or having bants?

Irish people are offending 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 NBD.

Those are just some of the 1,000 new words added to OxfordDictionaries.com in its latest quarterly update, which reveals current trends in the usage of language.

New entries include manspreading, when a man sits with his legs wide apart on public transport encroaching on other seats, bants, short for banter, and NBD, an abbreviation of no big deal.

Beer and wine o’clock, describing the appropriate time of day to start drinking the respective alcoholic beverages, and brain fart, a temporary lapse or failure to reason correctly, have also been added to the free online dictionary.

Hangry, an adjective used to show feelings of anger or irritability as a result of hunger, is another new entry. The word has seen its usage increase since 2012, with a big spike in April 2014 connected to a US study about low glucose levels making people cross.

Topical news terms have soared in popular usage. Grexit and Brexit, referring to the potential departure of the UK and Greece from the EU, and deradicalisation, the action of causing a person with extreme views to adopt more moderate ones, are also included in the update.
