Motmo is an acronym for Missing Out on The Moment. It's akin to FOMO (Fear Of Missing Out), but it is the result of actions which led someone to miss out on the moment they desired so much to
experience.
One example of this is people who go to watch
fireworks and then video it all on their phone. Rather than
experience the moment, they totally miss out on it. The way it sounded, felt and really was.
