Is there really that much difference?
Well, maybe not from the perspective of the poo-poo caca. But if I were to tell you I this really unattractive guy asked me out, would you think I was certifiably crazy because everyone knows turds can’t talk, let alone jump out of toilets and hit on people?
Well, I can’t see how they can be considered attractive, but, to each his own…
Best wishes,

We used this term in my frum girls’ HS (and yes, frum is totally unisex) in the mid-nineties, when the style for frum girls was almost exclusively ankle-length skirts, with the very occasional knee-length. At the time, I definitely thought it was ‘doody,’ as in poop, but later on, I’ve definitely come across ‘duty-length’ in non-frum publications, referring to mid-calf skirts in general. Wish I could remember where.
I should’ve checked with my wife before posting. It was me who questioned it on the basis of the “t” sound. My wife and daughter never felt it to be anything other than “doodie”, as in “yuccchh”.
Well, in Starfleet it can mean this, http://pics.livejournal.com/jane_says/pic/0005dg1r, or this: http://raidergirls.com/raiders_blog/wp-content/uploads/2009/11/uhura-skirt-trek.jpg. Take your pick.
You are frum! 
Googling pics for “duty length skirt” brings up this(see post #10)
Well, in an American accent (or, at least mine), “duty” is pronounced with two “d”'s, so it does sound like “doody”. I believe that this is the same accent feature that makes us pronounce the “Latter Day Saints” as the “Ladder” Day Saints.
Where are y’all from?
Provided that frum has exactly the same meaning in Yiddish as in Swedish devout is not a 100% accurate translation. It’s as good as you can get it, but it doesn’t cover the full meaning.
