I think it just means 'nah!' as in no spoken colloquially - but I may be wrong

Ιάκοβε, your answer is correct.  "Μπα" is an exclamation, common in oral speech.  One of its meanings is “nah”.  

"Μπα?" may also mean “really?”.  Here is an example where we express surprise and disbelief:

Η Μαρία πέρασε τις εξετάσεις.
Μπα, τι λές?  Αυτή δεν είχε διαβάσει ποτέ.

Maria passed the exams.
Really?  She never studied.
