Yeet is a wonderful word. It is used when:

1. You launch a object at high velocity
2. You need a fun thing to say
3. Something (usually an animal or person) leaves or moves really quickly

Yeet comes from this meme:

It quickly became an internet meme and something that you just say for fun.

(For some reason the actual meaning has nothing to do with the dance, but I can’t really explain how the internet works)

1:
Person: Launches object at high velocity
“Yeet!“

2:
Friend 1: “What a fun game today!”
Friend 2: “Ya yeet!“

3:
Person 1: Scares doggo by throwing pillow at it
Person 2: “XD that doggo was just like YEET!“

Yeet can also be used as ya-yeet or yeetus
