A person at a company, typically in some position of authority, who appears or claims to be busy but does very little actual work.
“Salad walker” comes from the stereotype of the female office supervisor that eats their lunch, stereotypically a salad, on-foot because they are “too busy” to sit down for lunch.
My supervisor is a salad walker. She’s apparently too busy to respond to our team emails, sign off on her paperwork that she tells us to do for her, or even tell us the new policy changes but is always taking time off for vacations.
This is the insulting term you call some dude who is acting real tough but you know that he is a total coward. He is softlike a salad and also has no hard crunch that nuts can provide in a salad.
Steve: "Now, shut your mouth before I do! Come at me, bro!"
Greg: "Fuck you, Steve! I ain't afraid of you! Salad no nuts! Yeah, that's what I said - SALAD NO NUTS!"
Steve: "I'm sorry, man. Please be my friend."
