I've heard people say it, speaking like this: "This would be a great solution to the problem, except that it would break the admin dashboard. And billing. And SSO. And partner test environments. And. And. And. And. And. This would break so many things I'm sure I could only name half of them if I tried."
Agreed--it seems likely that the user was writing dialogue, taking minutes, or something similar.
Skilled speakers frequently use repetitions of a word (like 'and') as an interjection[0]. It's a handy way of giving yourself a second to think without saying 'uhh' or 'umm' (which, for whatever reason, are considered 'bad' interjections), and seems to be a kind of defense against being interrupted.
Years ago in school, maybe about 1992 or so, I managed to make xdm (X Display Manager) crash and dump me a root window by simply holding down a key until the buffer ran out. I remember wondering how anybody didn't discover this before me. Similar behavior with the university phone system (repeatedly pressing '0') eventually dropped me an outside line that I didn't have to pay for (yes, for you young folks, we used to have to pay for long distance phone calls, on phones that didn't fit in our pockets).
I seem to remember that a few years ago some versions of either TouchWiz or Android, that you could overflow into unlocking the phone.
The number required was pretty high, but you could get to it by copy pasting an already typed (In the emergeny dialer) number for a while, crashing the lockscreen until the next reset
I always suspect that software I'm using is not really tested. If there are animations or whatever is happening asynchronously monkey bashing will trigger lots of issues.
You just reminded me what we found in college (on campus). We could dial out to the other college, then back into ours, and then externally to get free long distance calls.
Let's place bets:
A) The user just let autocomplete "take it away" (not sure about this one since they were able to access the console)
B) Pen Testing?
C) Error copy and pasting?
D) Actual dialog in a sci-fi post-apocalyptic love story where a robot discovers the Turing test and attempts to set itself into an infinite loop.
