What do you mean by "rice"?

Dry rice means eating. "Gan" is a popular word on the Internet now. Maybe it's because I think dry rice looks uncivilized, so using the word dry instead of dry rice will look more civilized. At first, this word was used in videos made by up, like some movies need subtitles, but I am worried that using dry words will make it difficult to approve, so. In fact, the meaning of "dry" originally meant that water had penetrated into the ship, but now it has become the meaning of eating when it is used in network language, and the meanings expressed by the two are completely different.
