Patrol can get boring sometimes, even if the whole fam is out together. So, as any group of teenage vigilantes would do, they make it more fun by making it into a stupid game. Like who can say the most popular culture references or famous catchphrases on patrol.
This essentially means that Dick pops up blocking an alleyway, pulling up with the Obi-Wan "Hello there."star Wars references are common to the point that "I have the high ground" doesn't count anymore. "Bats Assemble" has been used - (DC Marvel crossover, I know, and idc) - along with "Honey, where are my bataraaangs?", "The Man who Stole, come to die" (not one of Jason's best, he'll admit, but they were running out of ideas at that point), and many more.
They've obviously also done the 'who can capture the most people' contest, and who can take down the most people with the least hits. That one they do when they get bored in training too, just sparring and setting ridiculous rules like after you've been knocked down, you can only get up with a flip or in some other obnoxiously complicated way.
