What does "Betcha" mean?

[rome]

I can't find what's the meaning of the word betcha

[Narayanan Krishnaswamy]

'Betcha' is a slang. It means, if I remember right, a sort of challenging. I think, this is a corrupted version of 'I bet' or 'I bet you.'

You should find this useful to understand the meaning.

You should have given the sentence, so as to see that word in context to give you the meaning.
Look into a slang dictionary.

Hi Rome,

This word is part of a colloquial expression that goes: You bet your sweet life and in its contracted form becomes: You betcha used more commonly in American English. It is used as an expression of certainty and mean: Yes, you're absolutely right about that.
