Bruce purposefully uses slang because he knows it annoys his kids.
…
“Alright fam, let’s get going.”
“Bruce…did you…did you just say ‘fam’?”
“Yes, and?”
“Nothing, nothing”
…
“I got Scarecrow back in Arkham, it was lit.”
“Did you just describe throwing a villain in jail as lit?”
…
*henchman passed out*
“Haha, mood”
*Dick to Babs on the intercom thing* “mood is dead, we cannot say mood anymore, Bruce just used it.”
…
Jason: Penguin’s doing gun dealings again?
Bruce: He’s collaborated with Two-Face for about a month. Stay woke, Jay.
Jason: Don’t talk to me, your son, ever again.
I imagine this would turn into an arms race where the kids have to find new slang before Bruce kills it.
@the-fourtysecond-ctaeth they’re always scrambling to find new words or make up words just so that Bruce doesn’t know them but after a few days he has figured out a way to work it into his vocabulary just because he knows it angers them
