Well, while it may not be as socially acceptable for a girl to burp in public as it is for a boy in some places, it is still a normal occurrence. Girls have stomachs and intestines that produce gas. Sometimes, when they are in a hurry to eat or are in a relaxed environment like among close friends, a girl might burp. But often, due to social norms, girls may be more self - conscious about it compared to boys.
