ampreguous

The ambiguous or confusing physical appearance of a woman with a big belly that makes it difficult to tell if the woman is pregnant or just plain fat.

This question is not easily resolved due to the insult to a pregnant woman if it is implied that they look fat, and the insult to a fat woman if it is implied that they look pregnant. Thus, asking the ampreguous woman any leading question would be committing a faux pas. Furthermore, asking someone in the know could eventually get back to the ampreguous woman and offend her, so the question usually just goes unanswered.
