借來形容速度與強度

刺激的、火力全開的
喝下去的燃料
同一罐油，這次倒進人身上：把人當引擎，把飲料當燃料。所以一杯很猛的咖啡、一罐能量飲料，或是酒精濃度很高的酒，都可以這樣形容。語氣比較輕鬆，常見於美食和生活類文章。

adjective · C1
Used about petrol or other fuel with a high octane number. Fuel like this stands being squeezed hard inside a powerful engine without knocking, so it is the fuel sold for fast cars, racing machines and planes.
