What does YEET mean on Snapchat?

Hey there, could you shed some light on the meaning of the term 'YEET' when it's used on Snapchat? I've been seeing it quite frequently in my friends' posts and stories, but I'm still a bit unclear on its exact definition. Is it a slang term? A joke? Or perhaps it has a deeper meaning that I'm missing out on? I'd appreciate any insights you might have on this topic. Thanks in advance!
