Soupy describes something that has become too watery, thin, or liquid, like soup that hasn't thickened properly. When your oatmeal is soupy, it sloshes around in the bowl instead of holding its shape. When a cake batter is too soupy, it might not rise correctly because you added too much milk.

The word often suggests something went wrong: the mixture needed to be thicker but came out runny instead. A soupy mess of rain and mud might form in an unpaved parking lot during a storm. Fog can be so thick it's described as soupy, making it hard to see more than a few feet ahead.

You'll also hear soupy used more playfully to describe anything overly soft, mushy, or sentimental. Someone might call a movie soupy if it's packed with exaggerated emotions and sappy moments. The word captures that sense of something being too much, too loose, or lacking the structure it should have.
