The Eddie Bauer/L.L. Bean/Orvis pseudo-outdoorsy
men's fashion that evokes a rugged
lumberjack facade, when in fact the wearer is merely a
yuppie. The look is often accentuated with well-groomed beards, Land Rovers, and utility knives whose only real use involves the wine corkscrew.
The Yupperjack looks as if he could go outside and chop wood at any
time, when in fact he's more likely to flip the switch on the
gas fireplace in his 4000
square-foot A-frame "wilderness escape" cabin.
"Why's Matt wearing a plaid flannel shirt to the office today?"
"He's a Yupperjack."
