"Hershey Highway" Refers to the "Chocolate Road" which is in fact a man's anus.
"Road Warrior" = Flaming homosexual lolz.
These two phrases combined produce a very fulfilling burn which just rolls off the tongue and often spurrs spontaneous orgasms in nearby females within a 15 metre radius.
Guy 2 - "... Hershey Highway Road Warrior Rly?"
