Scottish Gaelic Translation

[Misstee]

Someone I know often ends sentences with a phrase that sounds like: "Oh Maha". Can any one tell me what this means, please. I've tried several online dictionaries but have no idea how to spell it. The person is just an acquaintance and I don't really know them well enough to ask.

Pronounced 'Maha', it's actually two words; 'math tha'. Math=good, Tha=is.

Thanks, Heathfield :-)
