-Having heavy eyebrows.
From mid 19th century: from late Latin "palpebralis", from Latin "palpebra" - ‘eyelid.’
Used in a sentence:
"I heard that she really has a thing for palpebrous men!"
Someone who has "heavy eyebrows" is palpebrous. Such a person may be rather winsome - Brooke Shields as an example. Or it may render someone somewhat less than soigné, such as in the case of Groucho Marx. I've even known a few chaps that look like horned owls if their wives don't intervene!
