In a discussion on a pick-up truck car wheel theft, one person gave an advice to the victim that he "should have bought some locking lugs". This advice was disapproved by someone else in the discussion and said that it's not useful, "all you have to do is hammer a socket on it and pop it off, not hard to do."
I'm trying to visualize how this works. What is a socket, how does it look like? All I know of a socket is the ones on a wall that you put a plug into in order to connect electrical equipment. Another relevant definition I found is "a device intended to hold an electric light bulb mechanically and connect it electrically to circuit wires." I'm not sure what this is, but I don't think it's what he's describing.
So you hammer this socket on the locking lugs, by the way, after looking it up I realized that the person may have misunderstood about locking lugs and I think he meant locking lug nuts, which is a fastener used to secure a wheel on a vehicle that requires a special wrench to remove it. So you pop off this lug nut after you hammered a socket on it. Pop I checked means "to suddenly break open or come away from something often with a short, loud noise". So I'm assuming this involves some kind of tool as well in order to pop it off? How does this work, what am I visualizing? What is a socket?
