In politics, a countermeasure to Free Speech protections whereby threatening information is discredited by associating it with already-discredited information.
Citizen journalists are publishing articles about how our healthcare reform bill is really designed to work in favor of our interests and at the expense of minorities! We can't censor them! Quick! Publish a bunch of Chaff about UFOs and a Flat Earth and link it to their sites! That way it'll look like only conspiracy theorists view this kind of stuff and no one will take it seriously!

Yes, I know that when you see this book about the War on Amazon it says that all the customers also purchased books about Nazism and Holocaust denial, but that's just Chaff intended to make it look guilty by association.

A stupid person; it refers to the lack of surface area on an individual's brain. The general thought is that the more surface area (wrinkles, creases, etc.) a brain has, the smarter the person is. Conversely, a person with a smooth brain (no wrinkles) has less surface area and would therefore be stupid.
That fucking smooth brain put his shirt on backwards again...

That smooth brain is dumber than a pile of shit.

A person kept around during the zombie apocalypse by a group of survivors as the designated bait when running from zombies. Usually a slower, heavier or asthmatic person without stamina. The idea is that he/she will be the person at the back of the group and will be caught by the zombies thus allowing the rest of the group to escape.

It has its origins in WWII radar counter-measures - bogus targets dropped by aircraft to confound enemy surveillance.
"We keep Bill around as Chaff, we don't have to run fast, just faster than Bill....."

"Who's the Chaff in this group? Look around, if you can't pick him out, it's you!"
