Reduction of and that, which can mean “along with some other stuff,” “the previous was just an example of more general case,” or (at least in Glasgow, Scotland) something like “I know this isn’t stated as clearly as it might be, but you know what I mean.”
Geographic distribution: Southwestern Pennsylvania (see above citations).
Origins: Possibly Scots-Irish. Macaulay (1995) finds it in the regular speech and narratives of Scottish coal miners in Glasgow, a principal area from which Scottish settlers emigrated to Northern Ireland, and from there, to the American colonies.
