Bellyache : What does this word mean? When you bellyache someone, you complain in a whining manner. In other words, you sound as if you are moaning. Here are a few examples. • Whenever I run into Pankaj, he bellyaches about all the work he has to do. • Some of your friends tell me that you bellyache about a lot of things. A person who is constantly complaining is a bellyacher. COURTESY : The Hindu (The National News-Paper) - India
