1. "Common sense" is something that is no longer "common"; it may have been bred out by rednecks, white supremacists, haters, or plain old "common folk". Maybe it is just ignored as an attempted stand against authority, maybe it is a product of anti-evolution, an anti-sensible change brought about by genetically inept breeding.
EX: Lacking common sense is exemplified by kids run around with sharp scissors or knives, walk in the middle of the road and FULLY EXPECT you to move out of their way - as if the sidewalk needs to be defined on this site before they can figure out that it is to be used by them, and that VEHICLES use the road, stupid parents that don't care, and don't care to know where their kids are lack common sense, drinking and driving. buzz driving, playing Russian Roulette, acceptance of Ebonics as a dialect or urban language is due to a lack of common sense by those who decided it was easier to give up than to teach their students properly, etc... The list goes on and on...

EX 2: It used to be common sense to do a courtesy flush but now when you walk into a bathroom stall (stall) you can't even breath b/c some iggit dropped a bomb sized turd into the toilette and did not flush it. Common sense is something that used to be prevalent in society, as a whole, but through time has diminished greatly for whatever reason.

EX 3: A great example of the lack of common sense is some person looking this definition up as "common cents", as I have heard it referred to, and ironically, I have seen it spelled that way.

Common sense is what -I- think others should know.
When you remove the tea kettle from the stove, it's common sense to then turn off the burner.

1) Something the general populous of Earth lacks.

2) The ability to discern what is right and what is wrong.

3) The ability to discern what is intelligent and what is stupid.
The blaming of obesity on fast-food restaurants and not on people who should know that fatty food makes you fat.

The term should speak for itself. A Sense which SHOULD be common to everyone. Usually refers to any sort of logic that should be obvious to anyone.
It is dangerous to play with sharp objects.

If you buy a Sega product you are just throwing your money away on something that will not have any new games released for it shortly after its release.

A mythical force that is supposed to bestow knowledge of the obvious. Unfortunately, humankind has proven, time and time again, that there is no such thing as common sense.
The People v. Common Sense:

Exhibit A-
Common sense should tell people that coffee is a hot drink, and that when spilling it, one should expect it to be hot. Common sense should also tell people that eating fatty foods makes you fat. Still, look at the recent pathetic excuses for "lawsuits" against some fast-food restaurants.

Exhibit B-
Common sense should tell people - even children - that TV shows such as "Power Rangers" are not reality. Two eleven-year-old boys, however, tried to re-enact a scene from the above-mentioned show by burying an eight-year-old boy alive in the ground, thinking he would grow back out. Duuuuh...I don't think it worked...oops!

Exhibit C-
Common sense should tell the Bush administration to take money from people who actually HAVE MONEY TO GIVE, but instead they choose to take it from people who do not have it.

I rest my case.

Essentially, common sense is seen as knowledge that most people (except babies and the mentally disabled) should know. This can apply to things affecting all humans, or it can pertain to certain peoples and issues. When someone does something that contradicts common sense, you tend to think, "Dude you are so stupid. Anyone with common sense would have avoided that."
Things that universally defy common sense:
-trying to breathe underwater
-staring into the sun to try to see it
-trying to touch a rainbow
-believing politicians truly care about the people
-telling someone with a bazooka to fuck off
-driving on the wrong side of the freeway
-being a hypocrite
-poking any dangerous creature

1) Putting the pieces together using the knowledge that one already has. Usually obtained by having actual life experiences, as opposed to sitting at a desk of in front of a textbook all day.

The only type of knowledge in life that is truly useful over 99% of the time.
1) Jimmy spent eight years at his desk getting his advanced degree in mechanical engineering. He was hired happily straight out of college making $105,000 a year, but ultimately failed at even the simplest of automotive tasks, since he lacks the common sense to so much as change his oil.

It also took him 45 minutes to find the entrance on the hooker he hired on a lonely Friday night.
