My Dad, being a knowledgable and cautious man would go out and check the engines and chat with the maintenance people before allowing us to board. He would occasionally point out items of concern- bald tires, dangling wires. The response was always the same, nodding heads, smiles and these words...sounding somewhat like: "May oh gwan chee."
Not speaking a word of Chinese, he got into the habit of calling the airline " May oh gwan chee". Years later we discovered that this was NOT the name of the airline. It is Chinese for "No Sweat."
