The word 'sideboob' has been recently added to the OxfordDictionaries.com.
However, the new formally born word hasn't made it to Oxford English Dictionary hardback just yet, the Daily Star reported.
According to the webpage, the word means "the side part of a woman's breast, exposed by a revealing item of clothing".
Words like 'YOLO', 'hot Mess' and 'amazeballs' are some of the 21st century quips that have also been included on the webpage.
