Tom is the blue-grey cat from Tom and Jerry, created by William Hanna and Joseph Barbera for MGM in 1940, whose exaggerated screams were originally performed by Hanna himself. Those yells became a defining part of slapstick cartoon sound design, recycled across decades of shorts, TV revivals and films. Short clips like this two-second version spread through Brazilian soundboards and meme pages under names like Tom gritando, where creators reuse the familiar panic to punctuate fails, scares and cartoon-style injuries without needing any dialogue or setup.
