Jaina is clearly latino slang.
I thought Jaina was her last name.
Miss V Jaina.
I assume that you made a sarcastic remark and do not truly believed it. Nevertheless the amount of laughs that you got on that very flat joke despite its sarcastic undertone, got me a bit worried and and in some cases it made me 'sigh'.
Naturally to differentiate each dialect and its use you have to study the language and or live with the people speaking it. And what i stated, is that i'm not capable of doing it, besides recognising this one very obvious thing and that was the core of this statement, that you used for this i-puddle of a joke. But what is more important stands behind my statement that you have not deduced for a joke:
Languages comparable in this attibute to DNA, if they spread across a great space tend to develop regional dialects over time and and with the passing of time they separate into different languages, while belonging to the same language group, due to agglomeration of regional changes. Some changes may develop in the native region of this language and spead into the whole language group while in some cases this may happen also for changes that accured not in the core region of the spoken language. Depending on the change and or its surrounding environment we can guess with a high probability the origin of the change and its spread with its path. Knowing that it derives from the word 'Honey' and also knowing the use of this word over time we can narrow down the population that uses the word and its spread in the spanish speaking world. Overall Latino is a bit vague in this case, but since the populations are extremely code exchanging, it is rather better applied than chicanos or the also possbible exil cubans or puerto ricans or other spanish speaking group in USA.
Why it is so interesting? Because it is Information theory at its most visible point in linguistics and the same applies also to lifeforms in biology, diseases or the mental / cognitive information process, like ideologies.
Learning and understandig such things can enable you to recognise processes around you and it enables you know the orign and the destination of this processes, before they exhibit their significant effects.
Therefore jokes as much as you like, but keep always in mind what you are joking about and why and how you do it.
