Taking the UNUSUAL capitalized words from POTUS’ tweet above, you get OCV.
Acronym for “One Character Victory”, which is a term in the video game world, specifially the game “Marvel vs. Capcom 2”. An OCV occurs when one player defeats his opponent with just his starting character and only that character without switching to a teammate.
