"John Q. Public is a generic name in the United States to denote a hypothetical member of society deemed a 'common man.' He is presumed to have no strong political or social biases relevant to whatever topic is at hand, and to represent the randomly selected 'man on the street.'
Roughly equivalent, but more pejorative, are the names Joe Six-pack, Joe Blow, and Joe Schmoe, implying a lower-class citizen (from the Yiddish schmo: simpleton, or possibly Hebrew sh'mo: (what's)-his-name)."
“Oh, I think they’re (critics) just not used to someone coming in from the outside saying you know what? It’s time that a normal Joe Six-Pack American is finally represented in the position of vice presidency, and I think that that’s kind of taken some people off guard, and they’re out of sorts, and they’re ticked off about it,�? she (Sarah Palin) said."
