When someone does something that isn’t very Plus Ultra of them to do. Like insulting someone else, or the Japanesename in general. Relates back to the anime “My Hero Academia”.
Susie: Bethany looks really weird!
Me: Susie, that’s not very Plus Ultra of you!
Catch phrase of UA High School in the anime "My Hero Academia" meaning to "Go beyond". In essence it means to be everything the world thinks you are and more. Never stop climbing, achieving, and being incredible in your own unique ways.
Meaning "More Beyond", and stemming from the Spanish Motto... It became a secret society of rich guys including Tesla and Walt Disney, who secretly made a plan to "create more beyond" and build a technocracy.
Also a scary RPG about pedo-trafficing at Disneyland... That's why Tracy Twyman named her inner-circle website membership Plus Ultra.
