The term 'catfish' has been doing the rounds for years - ever since Ariel Schulman and his brother Nev teamed up with Henry Joost to investigate Nev's long-distance Facebook crush.

But while the resulting 2010 documentary was a smash hit, spawning an amazing TV show (even if we do say so ourselves), 'catfish' was never actually officially a real word.

You'd be surprised how often that happens.

Now, though, the ultimate authority on words, the Oxford English Dictionary, has legitimised the term.

'Catfish' has been officially approved by the literary powers that be, and added to the tome - or, at least, the online version of it.

Here's the definition:

CATFISH
VERB
US INFORMAL

Lure (someone) into a relationship by adopting a fictional online persona:
''he was being catfished by a cruel prankster'
'a victim of catfishing''
[originally with reference to the 2010 documentary film Catfish, which concerns such a relationship]

Amazeballs, huh?

[related]Speaking of which, 'amazeballs' is another word on the OED's hallowed list of 2014 additions, along with other slang terms including 'adorbs', 'clickbait', 'cray', 'douchebaggery', 'fratty', 'humblebrag', 'side boob', 'YOLO' and the good old Geordie Shore favourite, 'hench'.

Should such slang continue to be in popular use in years to come, it will eventually be added into the proper, printed version of the dictionary. Stranger things have certainly happened - after all, they added 'muggle' in 2003.

Here's the full list of additions. WDYT?
