What is a SAMBONER?
A sandwich connoisseur from the Philadelphia area. A samboner will talk for hours on end about slab vs chopped cheesesteaks, Wiz vs American vs Cooper Sharp, broccoli rabe vs creamed spinach in a roast pork sambo, not to mention debates over sambo-producing venues.
Along with "sambo" (noun, sandwich) another variation of samboner is "sambone" (verb, to eat a sambo and assess its merits on video for other samboners).
"Any real samboner knows you need a seeded jawn to soak up the juices in a Roast Pork sambo." (Urban Dictionary)
