Definition of the word flash around

The origin of the phrase "flash around" can be traced back to the early 20th century, specifically the 1920s. At that time, the term "flash" was already being used to describe a brief and sudden brightness, such as the momentary flash of a camera or a sudden burst of lightning. The prefix "around" in this context indicates movement or circulation. It was likely added to "flash" as a way to convey the idea of something quickly and repeatedly flashing or shining around. This compound word "flash around" first appeared in the early 1920s, and its use was initially limited to the military context. Soldiers would use the phrase to describe the rapid and repeated flashes of gunfire or artillery, as if each explosion created a momentary burst of light that surrounded them. Over time, the meaning of "flash around" broadened to include other rapid and repeated movements or appearances. Today, we commonly use this phrase to describe anything that quickly appears and disappears in succession, such as fireworks exploding overhead or lights flashing on a festive parade float. In each case, the "around" indicates the omnipresent and dizzying nature of these flashes in our environment.
