The Oxford Dictionary defines it as follows:
v. Inhale and exhale the vapour produced by an electronic hookah head or similar device.
n. An electronic cigarette or similar device; an act of inhaling and exhaling the vapour produced by an electronic hookah or similar device.
Editors at Oxford found that use of the word has doubled in 2014 over the prior year. It can also be traced back to the explosion of the electronic cigarette industry.which topped $1 billion in sales in 2013 according to Forbes.
As the practice gained its own audience, a new word was needed to describe the trend, hence “e hookah head vape.”
“As vaping has gone mainstream, with celebrities from Lindsay Lohan to Barry Manilow giving it a go, and with growing public debate on the public dangers and the need for regulation , so the language usage of the word ‘e hookah head vape’ and related terms in 2014 has shown a marked increase,” said Judy Pearsall, Editorial Director for Oxford Dictionaries on their website.
The word was added to OxfordDictionaries.com in August, but is not yet in the Oxford English Dictionary. Editors are considering including it in the future.
The shortlist for words of the year according to Oxford also include: “bae,” used as a term of endearment for one’s romantic partner; “budtender,” a person whose job is to serve customers in a cannabis dispensary or shop; and “slacktivism,” actions performed via the Internet in support of a political or social cause but regarded as requiring little time or involvement
