The state of comfort one enjoys while being "invisible" in a chat program, such as gmail chat. Being invisible allows you to pick and choose who you send an im, instead of being peppered by people you don't really want to talk to.
-"Hey man, hit me up on chat if you're invisibliss."
-"Dude, i can't get any work done... my girlfriend won't stop chatting with me on im... it's non-stop!
Eyebrows that are there, but are basically invisible. Some people are born with giant, thick brows, others are born with invisibrows. Whether they're extremely sparse or super blonde, they are unfortunate.
"drawing your eyebrows on is freaky and gross"
"hey man, shut it. I was born with invisibrows. I look like a damned alien if I don't draw them on"
