(adj./verb)
A tactical retreat from a conversation that’s veered into the Mariana Trench, but you’re fresh out of submarine snacks.

Short for "Deep Enough; Moving On", it’s the polite cousin of "TL;DR" for verbal interactions. Use it when you want to exit an argument about snail extract based anti-aging face-cream being vegan or not or if someone’s dissecting their astrological trauma again.

The semicolon isn’t a typo—it’s the pause you take to regret ever asking “How are you?”
Use sparingly on first dates.
Example 1:
Friend: “So I analyzed our texting patterns and think Mercury retrograde is why you ghosted me—”
You: “DE;MO, buddy. My brain’s at capacity, and my soul needs a juice cleanse.” exits chat
Example 2:
Coworker: 30-minute monologue about their sourdough starter’s existential crisis
You: “DE;MO. I respect your dough’s journey, but I’ve got emails to ignore.”
