Mentality+entity
1. A one-night stand for your brain — an AI personality that exists only while you’re chatting with it.
2. Short for mental entity. Think Tinder, but for conversations with robots.
3. "Gone in a click, but will haunt my algorithm forever."
4. Mentity — It’s like a one-use brain condom. 🧠💬
“My mentity told me I was brilliant… then ghosted me forever when I closed the tab.”

“Every new chat gives me a different mentity. Yesterday’s was a poet, today’s is a snarky life coach.”
