@ehBeth,
I was just wondering if this could be used to women.
But the thing is, now I realize, it has nothing to do with sleepiness.
I got this expression from a blog which , it says, provides useful expressions,
and I even jotted it down to memorize it.
Maybe I should forget the weird expression then.
Without your comment, I would've considered it a very good and useful expression and tried to use it often.
Thank you so much ehBeth.
