When your stomach growls but you have no correlating sensation of gastro-intestinal activity leading you to believe it was someone else's tummy groaning.

Get the ghost growlmug. A ghost rule growl refers to the powerful note in the song Ghost Rule by DECO*27. Although the original song doesn’t actually use Hatsune Miku’s growl, people like to make compilations of stolen vocaloid covers of the song calling them “Growl Compilations”.
