In Chapter 9 of Lord of the Flies, how does Jack try "to tempt" the rest of Ralph's group to join the hunters?What symbolic reference could this have?

Jack decided to throw a party--a feast--and include all of
his hunters as well as those still loyal to Ralph. Jack seems to realize that the other
boys will join him and gorge themselves on the meat of the pig, and they will not want
to go back to Ralph afterward. It symbolizes the extent of the boys' fall from civilized
order and into the hedonistic lifestyle that requires no rules. Even Ralph and Piggy
decide to attend, giving in to their desire to fill their bellies. Ralph declares that
he doesn't care anymore who joins Jack. It is similar to an old Roman orgy (minus the
sex). The boys paint themselves as Jack sits like an "idol."
