Never come across vmc (sic) other than as vis. met. conditions but that's universally rendered as VMC. The asymmetric case has always been (and is only) Vmca or Vmcg. It would make complete sense if the correct acronym was used...and none at all when it isn't! Uncapitalised 'vmc' - and missing the a or g is a meaningless acronym. Even so I've never come across the result of exceeding that limit having a name, nor ever imagined it needed one. Is this a US expression? It certainly isn't widely known in UK or European aviation.
