I'm not knocking Sft's website, but you'll get rather more information about the phrase by clicking http://www.worldwidewords.org/qa/qa-myg1.htm (Cheers, S.)

Dunno where it originated from but my family used to say it in an act of surprise, like if you startled my Mum she'd say 'Oh my giddy aunt!' Bizaare, I know.
