Silented 

To have a thought or idea, and forget it right away. As if you came up with the idea while staring at one of the Silence, and then looked away.
Coming from Doctor Who, where the order known as the Silence are "memory-proof", so you can only remember them while you look at them, and you forget them when you look away. The Silence uses post-hypnotic suggestion to make people do their bidding without people realizing what they're doing or why.

Doctor: "Amy, Rory: I have a great idea!"
Amy: "What is it?"
Doctor: "Uhh… I forget…."
Rory: "Hah. You just Silented!"

Usually the nickname of someone who you are extremely grateful to you, even if you're not aware of it. Someone who is always friendly at first but will protect their friends if it means emotionally derailing anyone who happened to upset them. Often blonde and good-looking, they are smart, humble and will have no problem looking you in the eyes.

I wish that I had someone like SilentDecibel in my life
