I found said comment when trying to come up with a synonym for "white whale" which wasn't mildly offensive. See, I was trying to describe an introverted girl who enjoys reading classic science fiction, folk music, and travel. Since such a girl is almost certainly going to be fat (and if she's not she's probably not going to date me) comparing her to Ahab's nemesis seems problematic.
I also found a lot of sites helpfully suggesting that the term I was looking for is "beluga," which seems like it could lead to a sitcom plot: the protagonist finds the "white whale" he's been searching for, and she's quite fat. A friend suggests that's offensive, so he googles synonyms for "white whale" and affectionately calls her his "beluga."
