# Cube Glossary (Outdated)

From 2003-2006, with 349 entries. Today, I support the SpeedSolving wiki, where I am a regular contributor.

I believe this to be (as of 2006) the longest list of cube-related terms in English (the longest in any language is probably on Ishino's site). A lot of the definitions are not complete yet. I'd appreciate any help with collecting cube terms and definitions.

(to find out more about items categorized [puzzle], please visit TwistyPuzzles.com). Thanks to everyone who contributed to this glossary.

Can be given using programs such as Ultimate Rubik's Timer (programmed by Jess Bonde) - Seven Sins of Speedcubers
- Accoding to Duncan Dick, they are

"1.. Taking a cube to bed with you

2.. Solving a cube when you should be working or studying

3.. Intolerance of those who can't solve the cube

4.. Frustration at the stupid things people say when they find out you can do the cube

5.. Deliberately popping during a slow solve

6.. Talking cube jargon to those who have no way of udnerstanding

7.. Teaching other people to solve the cube"
