Almost everyone coins or uses expressions that make sense to only a few people. What word or phrase do you use most often that you have to explain the meaning of to others?
Oh. Well I coined the phrase, "internet fatality." It describes someone whom you've gotten to know fairly well over the internet, and they disappeared without giving you a reason, or answering any inquiring emails, or IM's.
Me and my best friend have had that happen, and we are the only ones who know it as far as I know. She thought I was clever.
