K'we'fil's[!]
Someone who is so amazing, they make even the most confident people doubt themselves.
He showed up to the basketball game and my best friend said, 'I'm gonna beat him,' and he did it in 10 seconds.
He said he couldn’t do the math problem, and then he did it while talking to his mom.
He said he was gonna fall asleep in class, and then he passed the test while sleeping.
