Truce!

I was having dinner last night when my housemate Arthur entered the kitchen and called to his friend Holger: "I call truce!" Now, Arthur is from France and studies computer sciences, so his English vocabulary is not that extended. I wondered how he had picked up the word "truce".
But when I entered the living room, I quickly understood. The boys were playing a war game on their computer and were taking a break. Many might say that gaming is not good for young people, but it can add something to our vocabulary!
