The Church of Tetris 

The Church of the one true religion. The acolytes of the Church of Tetris (CoT) believes that all should receive the joy that Tetris brings. Their core beliefs include helping others to understand and share in the glory of Tetris, as well as abstaining from "False idols".

(Quoted from The Church of Tetris homepage.)
"The Church of Tetris is founded on the belief that all people should receive the glory of Tetris. Those who know of the Glory shall have peaceful lives filled with wonderful things. Those without Tetris shall continue on as all humans do. And those who oppose Tetris shall be crushed in a rain of blocks from on high."

The CoT has even sanctioned a prayer to be uttered whenever worshipping the one true Tetris.

"You can worship Tetris anywhere you can take an electronic device. We at The Church of Tetris have even sanctioned a prayer, which we recommend you speak aloud before worshipping the great Tetris:"

Oh, Tetris, thy Glory great,
Give us today our daily blocks,
So that we may clear them.
And give us strength,
Through our gaps and mistakes,
To obtain a tetris.
Start.

Traffic Tetris 

When you come to a stoplight and make the conscious decision to avoid getting behind a dumptruck or semi and opt for the lane with 10 vehicles instead of just two so you're sure to move sooner when the light turns green.

Oh no! I got stuck behind the tow truck at the red light. I need to brush up on my "Traffic Tetris" skills.

The act of carefully rearranging items in the refrigerator in order to make more things fit. Particularly applicable to students and others with small or starter fridges.

Refridgerator Tetris 

The process of organizing a large amount of groceries that appear as though they may not fit in such a specific way that allows everything to fit in the refridgerator. Typically, a guest or a child will upset the order of the contents and refridgerator tetris will need to be played a second time.

"Yeah, man- there was so much stuff in the fridge over at Stu's house, it was like refridgerator tetris when I had to get the milk."

Uhaul Tetris 

The act of orienting ones belongings in the back of a moving truck in such a way that the entire volume of the truck is filled, front to back and top to bottom.

I didn't think we'd be able to fit the pool table, ATV, entertainment center, and waterbed all in this truck here, but all it took was some clever Uhaul Tetris and we got it all in there.
