The metaphor for "fast" often evokes imagery of speed and swiftness, such as a cheetah sprinting across the savannah or a racing car zooming down a track. It can also be likened to the fleeting passage of time, like a shooting star streaking through the night sky. These metaphors emphasize urgency and quickness, illustrating how something can move or happen rapidly.
