The first one that came to my mind was Tarah Kayne at the last U.S. Nationals.
On a more amusing/less depressing note, my two favorites of last season were by Kevin Reynolds and
Matteo Rizzo. I love a good storming out of the K&C, especially when it's totally unwarranted.
The Reynolds storm-out isn't on YouTube, but I found it on NBC Gold so I can describe it: Kevin has a mountain of curls piled semi-casually atop his head and is wearing a sleek black ensemble. He and McLeod look quite somber while waiting for the marks. NBC then cut to an interview with Nathan Chen, making me enraged that they edited out the storm-out. But, luckily, the video came back. The second the scores appeared, Reynolds stood up, making eye contact with no one, and strode off toward the exit. The best part is that he's walking in a really stiff, slow manner because he still has his skates on, so it's like an elegant slow motion pace-off.
As far as K&C moments that caused a meltdown on FSU even if they wouldn't be classified as meltdowns on their own*,
Scott Moir's comment at the 2012 WTT has to be on the list.
Also, there must be several Tsareva/Pogo examples, but I don't remember where they happened.
*To be honest, I'm surprised there wasn't more of an outcry within the skating community calling for Moir to publicly apologize in order to avoid being censured or getting, at least, a temporary ban from the sport. This was one of the most egregious examples of foul and degrading language I've ever seen, either in or out of skating. If I was a skating coach and one of my students made a comment like that at an international event, I'd immediately kick them out of my rink and method.
