When I was working the reference desk of a public library, a teenager once prefaced a reference question with, "hey, dude who works here." I had always thought a dude was someone who worked on a ranch, but since the library is on what was once the property of the nineteenth-century land speculator and rancher Henry Dalton, they may have been technically correct in addressing me as "dude."
“dude”......... You got that backward, a “dude” is someone who DOESN’T work on a ranch and has NEVER worked on a ranch before. Kinda like you if Mr Dalton had called you a “dude”.
