Fat joke

Once upon a time, a fat man went to a new friend's house to join a multi-faceted fat man who didn't care, and he kept eating snacks. At dinner, the fat man is busy eating. When the wax gourd was fried with meat, the fat man went to the bathroom because he was really bloated. That night, a man at the party was murdered. What's going on here?

The fat man is an autistic person, and his heart is very depressed. The wax gourd fried this day was so bad that a girl with a big temper scolded, "This wax gourd is disgusting!" " "The fat man in the bathroom was hurt when he heard this sentence, because he mistakenly thought that the girl was talking about him and insulting him. So that night the fat man picked up the murder weapon and sneaked into the girl's house.
