I came across the expression "the face that launched a thousand ships" that describes a heavenly beautiful woman but at then end of this web page, it says "The term is also often parodied":
Today, the face that launched a thousand ships is still most often used to describe the unsurpassed beauty of Helen of Troy, though it may be used to describe the beauty of any woman. The term is also often parodied.
So my question is: Can I use this expression to describe a female in a more sincere/earnest way, rather than in a mocking/joking way?
BTW: This comment in another question seems to suggest that this expression is mostly used in a joking way:
A related joke is the dictionary definition "Millihelen: Unit of beauty sufficient to launch one ship".
