This song talks about the relationship (it is not known whether it is loving or friendly) of a fisherman who goes to La Restinga at Christmas "to have a bottle with a pretty mermaid, with a beautiful mermaid". This relationship has its clandestine tinge, since that he lies (but like all liars, they end up finding out in the end) so that they don't know that he is going to meet the mermaid.
