A word's worth

One would remember that 'selfie' was named Oxford Dictionaries Word of the Year 2013. Some other words added recently to the Oxford Learner's Dictionaries show how technology and social media jargon are recognised universally. One of these words (as seen on oxfordlearnersdictionaries.com) is "lolz", described as an exclamation (in emails, comments on social networking websites and so on). It is "used to express fun, laughter or the feeling that something is amusing". Another word that will sound familiar to selfie lovers is "photobomb", which means "to spoil a photograph by suddenly appearing or doing something unexpected as the picture is taken". Among other words included were "contactless", "fracking" and "vape".
