عُفَافَةٌ

is the subst. from عَفَّ said of milk: (O, K:) so says IDrd: (O:) [according to him, it apparently signifies Milk that has collected in the udder:] and it signifies (S, O, K) according to another or others, (O,) as also ↓ عُفَّةٌ, somewhat of milk remaining in the udder (S, O, K) after most of it has been sucked. (O, K.)

And F explains العُفَافَةُ, with damm, by the words أَنْ تَأْخُذَ الشَّىْءِ بَعْدَ الشَّىْءِ فَأَنْتَ تَعْتَفُّهُ [as though signifying The taking thing after thing, by licking it up, or otherwise, from the ground, choosing the best thereof: but this mode of explanation is often used in lexicons to denote the thing, or things, mentioned therein; not the act: and I think that what is here meant is the thing, or things, thus taken: this, moreover, is agreeable with the general analogy of words of the measure فُعَالَةٌ; as is shown by many exs. in the Mz, 40th نوع].
