I really wish people could make it a habit to read articles.

The article defines the acronym and even mentions where it comes from.

True, but the definition is in the very last line of the whole page. For people unfamiliar with an ROC curve, which seems to be the target audience, it should be defined the first time it's used.

Edit: on navigating the site a little more, the previous section does define the acronym on its first use.
