Pepe the frog is from the Boys Club, a comic or children’s book; I don’t know, it just had a couple talking animals. The first picture of him with the feels good man caption was very silly and took off from there. Unfortunately pepe became a hate symbol after 15 years.
If you are not social and want to be, this is actually a good way to practice conversations. The idea is to pretend to be one side of a conversation and try to mimic what a person would say in a situation. It’s more practical with planned conversations, like TV shoes because those conversations are designed to lead to something. Casual podcast conversations may have more conversation threads that may end abruptly.
