look up any word, like fleek:
A rockstar of the coolest kind. Pretty much the biggest superstar you could find.
Joe: Hey Bill, did you see that rebeka?

A person who gets jumpy after consuming caffeine. A rebeka is often very gullible but very intelligent. A rebeka is often a word to describe a 'human google'.A rebeka is a self-taught doctor. A rebeka has tight abs due to plenty of laughter because of her bubbly personality.
I feel like a rebeka this morning.
