Here are some things I have invented that are absolutely pointless -

- The nickname "Gunty" for Guntrip

- InteGreat Technology - when I was learning JavaScript in my early teens, I invented a name for my scripts; that name was InteGreat. You see, they integrated greatly. InteGreat.

- The word "excellace" and the phrase "Good one, Craig" when not talking about someone called Craig. It is sarcastic too. Good one, Craig.

- The Bacon & Egg CrabMuffin and Sausage & Egg CrabMuffin. Similar to the McDonalds equivalents, but better.

- Sandwiches. Though people seem to dispute that a lot.
