Words Entering The English Dictionary

In the last decade, there have been a series of words added to the English dictionary which may come to a shock to people, due to their non standard use in conversation. 

Gathered from the Goliath website, it gives us ten different examples of words added, and the most 'dumb' ones too, for example:

• Bromance: 'A non sexual relationship between two men.' 
• Babymoon: 'A relaxing or romantic vacation taken by parents-to-be before their baby is born.'
• Derp: 'Used as a substitute for speech regarded as meaningless or stupid, or to comment on a foolish or stupid action.'
• Duck face: 'An exaggerated pouting expression in which the lips are thrust outward, typically made by a person posing for a photograph.'
• FOMO (Fear of Missing Out): 'Anxiety that an exciting or interesting event may currently be happening elsewhere, often aroused by posts seen on a social media website.'
• Selfie: 'A photograph that one has taken of oneself, typically one taken with a smartphone or webcam and shared via social media'
• Sexting: 'Send (someone) sexually explicit photographs or messages via cell phone.'
• Twerk: 'Dance to popular music in sexually provocative manner involving thrusting hip movements and a low, squatting stance.'
• Unfriend: 'Remove (someone) from a list of friends or contacts on a social networking website.'
• Totes: 'Short for totally'
• OMG: 'Abbreviation for 'oh my god'
