Pepe the Frog is a cartoon character that has become a popular internet meme (often referred to as the "sad frog meme" by people unfamiliar with the name of the character). The character first appeared in 2005 in the on-line cartoon Boy's Club. In that appearance, the character also first used its catchphrase, "feels good, man."

The Pepe the Frog character did not originally have racist or antisemitic connotations. Internet users appropriated the character and turned him into a meme, placing the frog in a variety of circumstances and saying many different things. Many variations of the meme became rather esoteric, resulting in the phenomenon of so-called "rare Pepes."
