budtender (noun): A person whose job is to serve customers in a cannabis dispensary or shop. This word has come to the fore following moves to legalise the drug for medical use in some US states. It combines bud - slang for marijuana - and tender - as in bartender.
normcore (noun): A trend in which ordinary, unfashionable clothing is worn as a deliberate fashion statement. Oxford Dictionaries said use of the word peaked in 2014 and remains 'very much alive' despite predictions from fashion pundits that the trend is over.
contactless (adjective): Relating to or involving technologies that allow a smart card or mobile phone to contact wirelessly to an electronic reader, typically in order to make a payment. Usage peaked in September, when the technology was rolled out across London's transport network.
slacktivism (noun): Actions performed via the Internet in support of a political or social cause but regarded as requiring little time or involvement, for example signing an online petition or joining a campaign group on a social media website. Oxford Dictionaries cited the Ice Bucket Challenge and the No Makeup Selfie as examples.
