Ignomolloquium

(noun) : The idea that there can be someone out there mentioning your name and/or talking about you at any given moment and chances are, you'll probably never know about it. A combination of in- (not), gno- (know), nom- (name), and colloquium (conversation)

Jake: Dude, it's so crazy how we're bringing up Dianna. I bet she probably forgot us from high school.

Matt: Yeah man, she probably doesn't even know we're talking about her right now. We're just another of her ignomolloquiums.
