Far from the literal meaning, there is an expression in Spanish to say that something or someone is annoying: “dar la lata” -give the can-. About the origin of this expression there are three versions.
One of them refers to a tin can in which the 17th century soldiers carried the papers accrediting their service to the homeland. They used to present them when they went from office to office asking for some financial compensation for their scars and exploits. It is also thought that it comes from there that “dar el rollo” -giving the roll- is due to the can that warned the roll of documents.
Another of them relates the moment in which prisoners were given a drink based on the leftovers of various wines. After the irremediable drunkenness, there was a tremendous ruckus, which was extremely annoying for the surveillance staff.
The third and last one affirms that the motive is located in the carnivals, where they dragged and they beat empty cans causing a great commotion. Similarly to the widows who were remarried for the second time also they were made to sound a bell.
