Pepe is a meme generated- by and large, from the folks at 4chan (alt right). The uber left have assigned various pejoratives and negative meanings to Pepe. The Deplorables have embraced Pepe and all of the derogatories assigned to the meme, just as the left assigned made up charges against Trump supporters like racist, homophobe, Islamophobe, misogynist, etc., that went nowhere. [my words]
During the 2016 United States presidential election, associations of the character with Donald Trump's campaign, white nationalism, and the alt-right were described by various news organizations.[14][15][16] In May 2016, Olivia Nuzzi of The Daily Beast wrote how there was "an actual campaign to reclaim Pepe from normies" and that "turning Pepe into a white nationalist icon" was an explicit goal of some on the alt-right.[17] In September 2016, an article published on Hillary Clinton's campaign website described Pepe as "a symbol associated with white supremacy" and denounced Donald Trump's campaign for its supposed promotion of the meme.[18][19] The same month, the two sources for Nuzzi's Daily Beast article revealed to The Daily Caller that they had coordinated beforehand to mislead Nuzzi (particularly about the existence of a campaign) under the expectation that she would uncritically repeat what she was told, with one saying "Basically, I interspersed various nuggets of truth and exaggerated a lot of things, and sometimes outright lied — in the interest of making a journalist believe that online Trump supporters are largely a group of meme-jihadis who use a cartoon frog to push Nazi propaganda. Because this was funny to me.".[20] The Anti-Defamation League, an American organization opposed to antisemitism, included Pepe in its hate symbol database but noted that most instances of Pepe were not used in a hate-related context.[21][22] [source] https://en.wikipedia.org/wiki/Pepe_the_Frog
