Not the above, certainly. A term of endearment, yes. Anything else, no. In the West 'Babber' means baby, obviously, but generally means 'mukker'; it is more general - 'right enough, west boy', would be an equivalent that nobody says. Or you could say 'Babber'.
'My word, your accent is from the West'
'Rather, me babber, tell any one else and I'll smash your teeth into your head'.
