The 'Pixar Mom Dump Truck Ass' meme refers to a long-standing internet observation regarding the exaggeratedly curvy character designs of mothers in Pixar and Disney films. The trend gained massive traction with Helen Parr (Elastigirl) from The Incredibles and has since been applied to various characters like Aunt Cass from Big Hero 6 and Mrs. Davis from Toy Story. The meme highlights the humorous contrast between the wholesome family nature of these films and the distinct 'thicc' aesthetic chosen by the animators. It is frequently used to discuss animation trends, character tropes, and the specific 'dump truck' physique that has become a recognizable signature of modern 3D animated parents.
