Something of deep quality that deserves credit of being both spectacular and fantastic thus 'Spectastic'
Football 'soccer' commentator: That goal by Steven Gerrard was spectacular and yet fantastic at the very same time infact it was spectastic.

Me: Have you seen Megan Fox in the new Transformers trailer?
Friend: No?
Me: She's looking pretty spectastic in it, to be fair.
Friend: Sweet.
