The exact opposite of sicknasty

Something that sucks to an extreme degree. Specifically, the exact degree to which something sicknasty is awesome.
That concert last night was terrible. I was expected to be wowed with solos and energetic theatrics, but instead they lip-synched with a shit recording to add up to one of the most sucknasty performances in recent history.
