No, you missed the point. The problem isn't "narg" or "flargling" - those are just random stand-ins for normal words. Instead the problem is that the description says nothing that isn't already said by the symbol name. Whether or now you know what "narg" and "flargling" mean, a documentation page for Nargflargler that just describes it as "Flargles the narg" provides zero additional information to you.
