Stock iron

A derogatory term used to describe players in the video game Minecraft that are wearing full unenchanted iron armor as opposed to something better such as enchanted diamond armor. It is often used in PvP game modes such as UHCs.

xX_MinecraftGod_Xx (wearing full enchanted diamond armor): lol kill that dude he’s just a stock iron
TryhardLuke72 (also full enchanted diamond): ok lol, brb
Stock iron: *gets absolutely obliterated in 2 seconds by TryhardLuke72’s diamond sword*
