Originating from the Barbie (2023) movie, it is a portmanteau of the Barbie character "Ken" and "Enough." To be Kenough means being yourself and recognizing you are worthy of love.
This word originates from the Barbie movie where Ken feels as if he needs to be something greater than himself, because he feels his true self isn’t great enough. However throughout the movie Ken learns being himself is enough hence the word “KENough”
You have time and time again tried to get stereotypical Barbie’s attention. But you now realize that it’s time to be your own doll. Try to figure out who you are without Barbie.
