What is the meaning of the word "CARL" that some add at the end of the phrase?
_____
Charles is 14.An old boy from the series "The Living Dead". Now in some Internet communities have become popular (well who how!) Comics "Carl and Rick" (and Google"), made from 3-4 frames of one episode scene and " funny inscriptions on top".
The point is that Karl is a "modern" child, accustomed to the internet, smartphones and other affordable "luxury", and Rick was born in the 80s and 90s (old athlete) and he had nothing like that. And so to any (completely normal for our days) request of Karl "I would like something" Rick answers with a feeling "Hat he wanted something? Karl, at my time there was nothing about it. And we did other, much simpler things. How much easier, Karl!" All comics are like that.
Both expressions are more than successful. More than good luck, Charles! And to better convey his thought to the child, Rick adds his name at the end. Added a name, Carl. To better convey the thought, the irony to convey all! It is ironic, Carl. You just have to see yourself once to understand everything! Let me see you, Karl. One time Carl. The comics are finally gone, Karl!
