This phrase is used to emphasize how something should never happen, no matter the circumstances. It's a more forceful way to say "never" or "no, this cannot happen." In this video, Jessica doesn't like the idea of her husband having female friends. She proceeds to tell her husband the rules she has for him when spending time with female friends. One such rule is his female friends cannot be gymnasts, cannot have been gymnasts, nor can they desire to be gymnasts.
