The regionally-famous SDJ is a plaid lumberjack shirt/jacket, named after the town of Salmo in the Kootenay region of British Columbia. While the SDJ is an archetypal 'Real Man's Jacket' and a classic piece of working man's attire (hence the Poor Man's Tuxedo theme), the term is intended to be an ironic mockumentary of the town of Salmo, (and indeed any equivalent 'no frills' town in North America) which is basic in the extreme. Salmo has also been referred to as an 'X-Files Town'...
A tall, well-proportioned woman with a svelte figure that probably has some kind of visual arts fellowship or is writing thesis on Shakespeare's sonnets. The only certainty is that a salmonback is beautiful, voluptuous, yet thin enough to have a visible backbone. The silent 'L' is sometimes pronounced depending on how gobsmacked you are by the salmoninity.
RUBE: Did you catch that salmonback? Pink? You're gonna miss it... Oh.
PINK: Sorry, Rube, I was too busy looking for DoodyStreet.
RUBE: There she is again!
PINK: No doubt a salmonback. You could play xylophone on the moll.
