It's not dirty really it's not! I have to say this is a spoof name. I live in a river bottom and I have a lot of fog and mist in the mornings. So I've always used the name Misty. For the last 6 months I've been chatting on the internet.
One of my dear friends has a gf that is Filipino and we got to chat one night. I really enjoyed learning about her culture and how it was to live in a new country. The next night she came home from work and ask her bf if they were going to talk to Moisty tonight. He didn't know what she was talking about at first. Then it dawned on him she couldn't say Misty in with her accent.
The boo comes from me enjoying scaring people when the least expect it. Mostly because I'm pretty quiet and reserved in group situations.
