1, Happy Fat Water refers to cola drinks. At first, a netizen posted content on the internet, saying that drinking water would make you fat, so many people would call coke happy and fat water, which means that coke can bring happiness to fat people. Later, many derivatives appeared. For example, potato chips are called happy fat chips.
It means calling high-calorie food and unhealthy lifestyle "Happy Fat House xxx", which is the self-mockery of Fat House. So fat house happy chicken (fried chicken) and fat house happy snacks (French fries, popcorn, etc. ) was extended. And also extended the "fat house loves animals"-cats.
