"Ye maun winny't in your ? (sounds like "leaf")

"loof" or "luif" which a book I have defines as "open hand"

'stak', I think, is 'sack' (word used in several versions)
the other word used in combination with 'loof/luif' is glove...but listening to Mary O'Hara, it doesn't sound like 'gloof', does it?

the closest I see are the versions that say either:

"Ye maun thresh 't atween your lufes,
And ye maun sack it atween your theis" (thighs)
or

"And ye maun sack it in your gluve
And ye maun winno't in your leuve"

I guess it was not always understood even BY Scottish speakers....and since ALL the 'suggestions' were impossible, I suppose any silly combination makes sense, hmmm?
