Damian using gen alpha slang to annoy his father (the best way to annoy us adults)
Robin: Batman?
Batman: Hm?
Robin: How tall are you?
Batman: Six-two, maybe six-four. Why do you want to know?
Robin: Just curious, because I thought you were six-seven.
Robin paused pretending to hear a vine boom. Penguin, cuffed and about to be arrested caught on quickly and let out a weary sigh.
Robin (cheese eating grin): Nope, you’re not six-seven. I wonder who we know that is… six-seven!
Robin snickered, waiting for the terrible new slang line to hang in the air. Batman stopped talking, silently shaking his head. He began wishing he had let Damian be home schooled away from slang of his generation.
Batman: I thought when Riddler explained this generation's random gibberish I'd stop getting headaches when hearing it. Nope.
Robin: Whew, glad that didn't happen. That's very-
Batman: Don't you say the P word!
Penguin: My nephew’s been spouting slang like that, and I have yet to find out what it means. All I know is it pisses me off when kids say it. What does it mean?
Robin: What I've been informed, it's referring to a basketball players height. Six seven and then we move our hands up and down, but I'm not doing that second part. Six seven!
Penguin: Huh, look at that, an answer that barely explained anything and made me pissed off. That's impressive, kid.
Robin (bowing his head): Thank you.
Batman: I don’t want to agree with you on this. I really don’t want to agree with a criminal.
Robin: That isn’t very poggers, is it, Father? Poggers!
Batman flinched hearing the 'p' word.
Penguin (chuckling): Okay, that word was funny.
Batman: Alright, back to disagreeing with you. The universe makes sense again. Robin, stop quoting slang, you don’t like hearing it either.
Robin: Yes, that’s true, but it annoys adults, and I’m willing to sacrifice my usual restraints to annoy adults. Like you, because I love you, Baba.
Penguin: Aww. He got you with the cute act?
Batman (facepalming): Yeah, it’s working too. I thought my first Robin had weird slang, second robin the words they uttered were odd, but I liked them, third Robin he didn't subject me to that, but with my youngest son I can't escape this.
Robin (patting his father's leg): Sorrows, sorrows, prayers.
Penguin: Every time I talk to you I'm thankful I can't have kids.
Source: My nephew won't stop saying this stupid 6'7 joke! I can't be that mad at him though. As a Gen Z, we had some cringe slang too lol.
