Doctor Who has been a staple of British culture for over 50 years, and now it has officially infiltrated the language -that's why the Oxford English Dictionary will be adding the word Sonic Screwdriver to the newest editions starting in June. In the announcement, the OED joked that it only made sense given that the dictionary itself is a lot like a certain blue box in that it is "blue, much bigger than it looks from the outside, and ‘the gateway to everything that ever was or ever can be’…showing you the whole of the past (and much of the present) of the English language."
Sonic screwdriver isn't the first Whovian term to be included. Already in the dictionary are TARDIS, Dalek, and Cyberman. You can read the announcement on the OED blog.
