Big Iron: A firearm, specifically a revolver. Due to the thick metal used in creating old-style revolvers such as the Colt Peacemaker or the newer Ruger Blackhawk/Redhawk, and partially due to the weight of the weapon, they earned the nickname "Big Iron." This phrase became largely popular after Marty Robbins' widly successful gunfighting ballad called "Big Iron."
"No lone dared to ask his business no one dared to make the slip, the stranger there amoung them had a big iron on his hip"
If you’re googling this, it’s probably because of a Larry Stylinson reference. It refers to a clip of Louis Tomlinson where he compares the fan rumours of his and Harry Styles’ relationship, to conspiracies about iPhones. However the way he phrases it has led many “Larries” to believe he was lying. They believe it was a poorly attempted cover up. But oBviOuSlY 🙄 Larry isnt real.
(It’s not used in sentences other than to make jokes about bad liars)
