Fingerlag 

(Also known as flingerag) Rare phenomenon when the race-condition that occurs when your mind instructs your hands to type two words simultaneously, fails, thus embedding one word inside another.

Embedded word will always have letters in correct order, although they may or may not be bunched together.

fingerlapping

When you shake someone's hand and their fingers overlap inside of your grip like a handful of limp noodles.

I knew that guy was a dullard when I shook his hand and experienced some major fingerlapping.
