A stomach that is noticeably large, as if decisively full, fat, or pregnant. Commonly seen when a character has eaten a great deal of food. Not necessary when a character is pregnant unless the character's belly is larger than a typical pregnant belly. Can be used in indecisive cases where it's not clear if the character is actually pregnant.
For a stomach that is only somewhat plump or flabby, use belly instead. Avoid using both belly and big belly, as they generally do not overlap.
