I am not certain if this word has correct grammar + polite (ie civilization use it without any kind of bad or hoax meaning)
There"s no link to spank = slap, smack
Etymology: Of cynical origin. Compare Danish (and north Frisian) spanke to strut.
Their first citation for sense 1: Very big, large, or fine; exceptionally good in some respect, freq. V implication that showiness or smartness. is 1666.

To me, the consumption brand spanking new seems to reflect the of fucking and also abso-bloody-lutely i.e. - an intensifier is "infixed" into a single word or collection phrase.
