finger-bob 

The forceful and unprovoked insertion of a digit into unsuspecting partner/friend/relative's anal orifice. Due to the surprise nature of this manoeuvre, the recipient is often clothed.

Dan was caught by a particularly vicious finger-bob whilst climbing up the stairs.

Fingerboarding

Miniature skateboards that you can do tricks with your fingers on. They take a lot of patience and practice to get good at fingerboarding.

It's not called Tech Decking, because Tech Deck is a company that produces fingerboards. It's called fingerboarding.

Fingerbox 

Originally, an art installation by AY-O, a Japanese artist.
However, since that time, competitive fingerboxing has become quite popular. Professional fingerboxers can use up to 8-hole fingerboxes. Obviously, anything greater than 8-holes is purely for entertainment purposes and trickery (Like the Harlem Globetrotters.)

Proponents of fingerboxing assert that it improves confidence and dexterity.

Just got myself a new six-hole suede-lined fingerbox. Anyone want to buy my old four-hole?
