In 2014, a video was posted on Vine showing a boy doing a dance while someone says “yeet”. It came to be known as the yeet dance.
The following year, yeet was in widespread use as an interjection, signifying approval, alacrity or excitement.
More recently, yeet has been used as a verb. I thought it might just be one of those internet things that don’t appear in real life, but my daughter’s friends are saying it so that’s where we are.
It means to move quickly, to act with mad abandon. It can also be used transitively, meaning to throw, to shove. One can also “yeet on” someone else.
It remains an extremely informal term, but you’ll see it on forums, Twitter etc.

Jul 31, 2018 - If you didn’t know what Matt was doing he was yeeting the other tom out XD.
Urban Dictionary has entries for Yeet! dating back to 2014, but there are no entries showing its use as a verb before 2018.
There are some resources online that claim the past form is “yote” and the past participle is “yought” but I can find literally zero examples of these outside such resources
