Formerly, a species of snake; now more commonly referred to as any individual whose devious and deceitful nature is readily apparent, and as a result, they can't follow the straight and narrow. Instead, they sidewind you! They can't be trusted as far as you can throw them, they perpetually prevaricate, are prone to larcenous activity, etc. In essence, they are "disingenuous disciples of duplicity."
Yet another term coined by V.R. of a regional northeastern supermarket chain.
The usage of this word amongst his peers beggars belief!
Hey, cousin...listen! The nickel-dickin' sidewinder in aisle 2 just stuffed a tenderloin down his, how we say, trousers. Brutal, baby, brutal!
Those who come across this site and read this, who work at this supermarket chain, will readily identify with this and laugh their arse off!
