An individual who consumes, nay attacks, a buffet with the vigorous and unrelenting nature of someone fighting for their very life.
Leaving the table(s) both empty as well as damaged, these people leave nothing but napkins in their wake and chill the soul of restauranters who offer 'all you can eat'.
Thomas: "Holy Spaghetti Monster, that person must be hungry! Look at her pile up her plate!"
Mr Sweden: "Oh yes, she's a true Buffet Slayer"
Thomas: *shrieks in fear*
Mr Sweden: *urinates self whilst frantically brushing crumbs from jumper*
