(CNN)Here's an excuse to say, "yeet" -- or "oof" -- both of those words are now officially in the dictionary.
Dictionary.com just added more than 300 new words and updated definitions, which capture a wide range of emotions expressed throughout the past year and include some slang terms we picked up along the way.
Building off the online dictionary's spring additions, the new round of terms and definitions relate to the Covid-19 pandemic, race, technology and pop culture.
"It's a complicated and challenging society we live in," John Kelly, managing editor of Dictionary.com, said in a news release. "Language changes to help us grapple with it."
While Dictionary.com already had several Covid-related terms, there were still a few that needed to be added to the list.

Dictionary.com noted that it's important to recognize how society has evolved, while also welcoming some fun.
