Click

To Click: To meet with good (or bad) luck. A word in universal use with every kind of meaning at the front in the war. To "click" might mean for instance, that a man had succeeded in something, had secured a good job, had made his advances or "got off with a girl," had got into trouble and been punished or had been wounded and even killed. An example would be "Poor old Tom got clicked by a sniper this morning."

"To click a Blighty" was a usual term for a wound which meant a man being sent to England. A possible derivation of the word is from the clicking or "engaging" of wheels in machinery.

With a click: Smartly. A phrase adopted in allusion to a drill-ground word of command that in certain exercises the heels should come together with a "click" which was parodied variously. For instance, someone showing pleasure at getting good news, "His ears went back with a click."
