I see. I think I'm starting to understand the situation now. The outline of the person in that picture looked like Kasuga, so even though 運だけの春日 is a slang, I made the assumption that the message was sent to Kasuga in the literal sense from the beginning, but given that slang is widely used casually as an insult, (which was really new to me) now I've changed my mind that it's very likely that it has nothing to do with the comedian Kasuga, which significantly changes the speculation about what is intended to have been 生やすed. And as you said, considering the contrast with big breasts, I agree with the opinion that "a dick" would be it and this might be a message from a a viewer to an artist who added it to some character.
I sincerely apologize for my dumbness.
