Hindu is a religion, path or to be precise 'dharma'. It is not a language.

You become a Hindu when you say "I am a Hindu." There are Hindu nationalists who say that it is impossible to convert to Hinduism but according to IndiaDivine.com what they say is not true. According to most Hindus people become a Hindu by being born.
hindu is not a language, but a Religion. You can say accha in hindi though.
Apparently, "mad" or "crazy", though it can be used as an affectionate term.
If you can say Christmas is Christian Diwali then it is perfectly fine to say that Diwali is Hindu Christmas :)
