master pasture

One who masters the art or grazing (an expert grazer); someone who sits at their desk and stares at the computer screen all day, smokes a pack of cigs and is a slug. Can also be someone who just does no work that day and is grazing the pastures...

"Joe are you working today?"
"Naw bra I'm just grazin'"
"Damn, Joe you are such a Master Pasture!"
