The Ash Pedreiro meme, widely known as 'Dat Ash,' features an edited image of Ash Ketchum from the Pokémon anime with a predatory and exaggerated facial expression. Originating in the Brazilian internet community, the name 'Pedreiro' refers to construction workers known for their infamous catcalls or 'cantadas.' When the image crossed over into the global meme sphere, it was rebranded with the pun 'Dat Ash' to express intense attraction or lust toward a subject. It is typically used in image macros to react to something desirable, serving as a humorous, albeit creepy, representation of being completely captivated by someone's appearance.
