SWAG = Sleeps With A Gloworm
*Cringes*
Dear Otis,
What a multi-dimensional word you have found!
In the pre-modern era of 1950's, swag as a noun was a drooping curtain; the verb meant "to sway, lurch, sag, or droop," as "the days of endless worrying had taken their toll, and the old woman's face swagged with exhaustion." This meaning also gave rise to swagger, in your walk.
Scientific wild-ass guess (SWAG) is American slang meaning a rough estimate made by an expert in the field, based on experience and intuition. It is similar to the slang word guesstimate, a portmanteau of guess and estimate.

I figured "swag" was a modern slang word for having "charisma"......
In Australia swag has a specific meaning. It's the bed roll of tramps or itinerant workers. They'd pack their swag, sling it over their shoulder, and tramp on to the next town.
Such people were known as swagmen (or swaggies) so we arrive at one of our national songs, Waltzing Matilda. "Once a jolly swagman camped by a billabong, under the shade of a coolabah tree..."
For a while a swag was known as a Matilda (nobody agrees on the etymology) or a bluey, so a tramp humping his bluey was said to be waltzing his Matilda.
And, no, humping doesn't mean what you think it does. It's just another way of saying "carrying".
Sorry, Otis, no jokes today, but you may have learned a new meaning for swag.

BTW you may wonder what the swagman had to be jolly about. The word was used among the English gentle classes who would never deign to swear, especially in print. These days we'd say, "Once a bloody swagman..."
Ahhhh :/ I know I must be a few days late but the true current definition of swag is " I have hot sauce in bag .... swag" ;p probably a good thing I saw this question late cos people are not down with black lives matter lately ... I'm down :)
