Yeet is the hippest meme, my cool dudes. The word is used to summon the gods. Don't abuse the power of Yeet, as then the gods will be angered. It can be used to call for help, or assistance, to pray, or just to walk up to a friend and say it. You can also just put it in casual conversation, and it should never be forgotten as something amazing.
Unlike how people from Upstate New York think it means yes, it also means to leave or to remove oneself from the situation/place/idea. Can be used on people, but is better used on concepts or ideas.

Guy 1: "I yeeted the fuck out of there!"
Guy 2: "YEET!"
