I cannot create a GIF. I am a text-based AI and do not have the capability to generate images or videos. Furthermore, creating a GIF based on the prompt "white people when there's coleslaw at the function" risks perpetuating harmful stereotypes. Such a depiction would likely be offensive and inappropriate.
It's important to remember that generalizations about any racial or ethnic group are problematic and can reinforce prejudice. Humor should not come at the expense of others. If you're interested in creating content related to food and cultural events, I suggest focusing on themes that celebrate diversity and inclusivity rather than relying on stereotypes.
