It's either some 60's slang, or Stan Lee thinking that's what young people sounded like, and I get the feeling it's the second one lol.
The context is not what it looks like, it's something about breakups, even then what May says sounds weird even in that context lol.
I always found it ironic, 'cause Batman's cartoon is seen as the better one overall, but Justice League got so much from Superman's and not much from Batman.
Think there was something to do with the other Batman Cartoon being made around the same time, 'cause I hear DC didn't want the same villains showing up in two different cartoons for some reason, which would explain why Joker stopped showing up, but that sucks.
I should watch that Heart of Ice though, see if it really deserves all that hype lol.
Great Divide is such a snorefest that in the episode that has the characters going to a theater to see the some play about Avatar's adventures, they rather blatantly skipped over that story, so that showed the producers knew how much that one is disliked lol.
Avatar Day, I don't think it's that bad, but it's certainly one of the more forgettable episodes, although I did laugh on the trial, when the characters were trying to prove Avatar Kyoshi's innoncence, then when she suddenly shows up, she immediately says something like "I capped that Chin the Conqueror bitch", even funnier in the last episode when Aang talks to her and how she technically didn't kill him, she replied with "Nah, no difference, I capped him".
While it's nice this cartoon made Darkseid become known to the general public, sucks that as a consequence he's now Superman's bitch.
