One usage of PMO is "I PMO every time I watch that movie!" It expresses how something can be so funny or surprising that one is rendered incapable of breathing because of laughter. Sharing a lighthearted reaction to a funny event-a movie, joke, or story-is what it means. The message is very effective in bringing home just how much one enjoyed the event. It helps to strengthen relationships with friends as they are shared through humor and have unique memories.
