Explanation: That is, the appetite of a skinny person is almost higher than that of a muscular person. In the picture there will be a normal sausage eaten by a muscular person and a big sausage eaten by a skinny person.
This image shows two simple, cartoon-like illustrations of male stick figures with a caption at the top reading, "Only boys understand."
The top figure is drawn with a larger, rounded body, while the bottom figure is a thin stick figure. Each figure has a corresponding shape to its right: a slim vertical shape for the larger figure and a wider, oval shape for the thinner figure.
The image humorously suggests a concept that only boys would "understand," likely implying something related to body proportions, possibly relating to perspectives on body shape or physical changes over time.
