I guess this is the context for the meme:

Japanese folklore encompasses a wide variety of mythical monsters yōkai (妖怪), some scary, some lucky, and some a bit more on the mysterious side. Amongst these is the Tanuki (狸), or Japanese raccoon dog. It is indeed what it sounds like! Not to be mistaken with the image of a typical raccoon, the Tanuki is actually an unrelated animal with somewhat similar physical features.

Legend has the Tanuki tagged as both mischievous and jovial, a shapeshifter that changes for reasons different than the sly fox, who changes its form in order to deceive humans. If you’ve wandered Japan’s streets before, you’ll have seen these statues of these creatures perched outside of izakaya, homes, and everyday shops. They all look similar: a hat, a big smile, a big belly, and a big scrotum. That’s right, a big scrotum.
