Shit-eating grin
A stupid grin that makes you look so clueless that you enjoy eating shit on a daily basis without realising you're a complete putz.
People who call tech support don't even try to learn the basics of using a computer. I picture them sitting at their desk with a shit-eating grin, then headbutting the screen.
