Also, for my family, a verb meaning "to fit everything perfectly into the (car trunk, dishwasher, dresser drawer, etc.), usually requiring multiple attempts."
Usages: 1) "Honey, I can't get all the suitcases and the cooler in the back of the car. Can you tetris it in?" 2) "It all fit in the car on the way down, but it won't now. I think we had it tetrised in so good, it won't happen again."
