Yesterday marked a new era for the cultural phenomenon that is 'side-boob', after it made its debut in the Oxford English Dictionary. Yup, that's right.

For those who aren't in-the-know, side-boob (note the official hyphenation) is often referenced when discussing situations in pop culture where a female is photographed – usually from the side – wearing a dress or top that is a little revealing around the breast area.

As you can imagine, Hollywood is rife with side-boob. Rihanna, Reese Witherspoon and Lindsay Lohanhave all sported a healthy portion of side-boob on the red carpet at some point in their careers. 

And now, the OED has clearly seen fit to make it an official word.

Welcome to the world of words, side-boob.
