Similar to "jazz hands," a cheer/dance movement of the fingers with palms out and fingers moving quickly back and forth. If done wrong it looks like a nervous wave of the hand. If done correctly, it draws attention to the dancer.

One who knows the ins and outs of finger dancing in the cunt ring. He or she is considered a professional at foreplay, and always satisfies the boxholder by pummeling her cunt box, or ass box, so strategically and to such orgasmic heights unfelt of before, that anyone involved or voyeuring instantly declares a knockout (KO). Finger boxers usually have sticky, smelly fingers.
Julie tells her friend, "Shawn's a real professional finger boxer. He busted up my cunt box and knocked my orgasm lights out last night! It was sooo great!" Julie's friend replies, "So, he TKO'd your pussy, right girlfriend?" Julie giddily shouts with emphasis, "NO! He KO'd my pussy bitch!!!"

When one tries to do actions on touchscreen immediately after picking their nose. The booger remnants on the finger cause the finger to stick to the surface of the touchscreen.
I was about to get a top score on my tablet when I picked my nose and forgot to properly clean off my finger...booger finger.
