Cách sử dụng
Bellyache means to complain or be upset about something. It's like when your stomach hurts, but instead of your actual stomach hurting, you're just complaining a lot. You can use it when someone is whining a lot or being negative about something. For example, if your friend is constantly complaining about how hard their homework is, you might say "Stop bellyaching about your homework and just do it!"
