Snogger is in the online Oxford, although the entry says only "see snog". It's also in Wiktionary.
I'll accept that it's a word, but I'm not convinced it's a candidate for common word, even leaving aside the regional issue. Admittedly, I don't have access to a language corpus derived from reality TV shows. The only such show that I watched for a couple of seasons was the Australian version of
Masterchef - I'm pretty sure the word
snogger was never used on that.
In the News on the Web corpus there are 21 instances of
snogger, but all bar three of those are quoting the actor Emerald Fennell, who said of her casting as Camilla in
The Crown:
I absolutely love Camilla, and am very grateful that my teenage years have well prepared me for playing a chain-smoking serial snogger with a pudding bowl hair cut.
One of the other three quotes, from the
Daily Mail, was:
Perhaps we should not be surprised that the union of Irons, described, somewhat euphemistically perhaps, by friends as a' serial snogger', and Miss Cusack, 61, has long been rumoured to be an' open marriage'.
It seems
serial snogger has become a journalistic term hinting at something more amorous. Another set phrase may be
frog-snogger, at least to the extent that it appears in two book titles:
Princess Frog-Snogger (2016), by Tommy Donbavand, and
The Frog Snoggers Guide: A Guide to Getting Along with Toads (2009), by Susan Lancaster and Shane Orford.
The OED traces the use of
snog back to 1945 and
snogger back to 1965, but the earlier citations suggest a broader meaning: any kind of courtship or cuddling. The current meaning seems to be exclusively passionate kissing.
Regarding the different connotations of
snog and
kiss, the
Separated by a Common Language blog related in 2010 how someone, presumably American, having learnt on a dictionary's Facebook page that
snog is a British word for
kiss, posted, "I'm gonna go snog my kids.........*snog* (love it!)" As the blogger, Lynne Murphy, concluded, a little knowledge is a dangerous thing.
Anyhow, I'll add
snogger to our accepted words, as a rare word.
