Beneath an article reporting on an air pact with Ceylon (The Argus, Melbourne, 14 January 1950), a short column-filler adds to the mystery of the meaning of 'snog', and perhaps lifts a corner of the veil concealing the word's origins:
A Sinhalese woman ' recently returned gave a great tourist boost by saying Australia was extremely cheap and Australians very fond of "snog."
I telephoned the "Ceylon Times" to discover the meaning of snog, and a reporter explained that snogging means cheek-to-cheek dancing or "petting to music."
Very little can be concluded from this--only that a Ceylon Times reporter in early 1950 either knew the meaning of 'snog' or was willing to have the Aussie reporter on about it. And that conclusion comes with the proviso that the Aussie reporter did not make the whole thing up. The column-filler does suggest, for those willing to make great leaps from small promontories of evidence, that the term was in use, perhaps with a variety of meanings, in 1940s Ceylon.
To construct a rickety catwalk over the abyss containing the origins of 'snogging' (from which height we can perhaps at least overlook those origins), this dialectal sense, and these dialectal uses, of 'snug' suggest a possible connection, particularly considering that 'snog' is one dialectal spelling of 'snug':
(From The English dialect dictionary, being the complete ... v.5. Wright, Joseph, 1905.)
Those uses, and the sense thus attested, were collected from 1800s Cumberlands and Suffolk English dialects, where "Cum.3" references Wright's authority from
and "Suf. (C.L.F.)" Wright's authority from a correspondent,
The dialectal uses of 'snug' in the sense of 'nestling together; hugging, fondling' are not exclusive of, but rather complementary with, the Ceylon origin and sense of 'snog' relayed via The Argus, due to the long-standing and pervasive British influence on Indian English.
Note that, for the verbal sense of 'snug' attested in the Cumberland and Suffolk dialects by Wright (that is, by his referenced authority and correspondent) as shown above, the alternate spelling, 'snog', is not attested in Wright. This is where the planks of the rickety catwalk break, allowing not a more convincing glimpse of the origins of 'snogging' in the abyss but rather the suggestion that we may fall in by pursuing it farther.
