I believe this is an example of what's known as "pig latin". Pig Latin isn't a form of Latin at all, it's a way of "twisting" English (and perhaps other languages) so that you're essentially speaking in code. Other people who are familiar with the rules of Pig Latin will understand what you're saying.
I suspect the phrase you've mentioned from UXM means "No powers".
A couple of links that define Pig Latin and provide some of the rules:
I never picked up on that, Seldes! Wow, that explains more than I ever thought would come out of that... Also, with that comment, it would seem Storm is taking on a bit of a leadership role, huh? She's keeping everyone in check when Scott isn't around... Very cool.
I think I remember seeing some Pig Latin being used in one of the old Marvel cartoon shows. But I picked up on that when I read it. I don't know Pig Latin, but some things I can figure out on my own.
E, I've heard of pig latin, sure, but I never put it together that Storm was actually using it in that panel... I thought she was talking about paying for games on the boardwalk or something.
