Chewie, also known as Jesse, is a very mean, very rude person. But he’s still one of the most loveable people on the internet. He’s funny, has the cutest laugh of all time and runs a memepage (@burntvagina.jpg). He also streams on twitch. If I knew him in person I’d date him.
More than the "best". It's a combination of extraordinaire, amazing, exquisite, outstanding, wonderful, marvelous, magnificent, superb, first-class, in addition to beautiful, dazzling, adorable, delightful and lovely!
Example:
Mom: "That's me, the Chefest Chef Juju!"
Me: "No mom, you can't keep making up your own words to compliment yourself, you narcissist!"
