A vegetarian is someone who does not eat any meat of any type (steak,pork,bacon,KFC,you get the point)and instead decides to eat plant life (cucumbers,pears,corn,tofu,etc.)Most vegetarians are NOT stoner hippies, nor fuckheads who try to spread the "meat is murder" mind-state. if a vegetarian is publicly announced,it usually ends up a "dick-fight' between said vegan and a crowd.

a person woh eats no meat or poultry products. and on most parts wears no fur or leather. NOT THE SAME THING AS A VEGAN!

1. A person who does not eat meat of any kind, but still eats eggs and animal products.

2. A douchy self-righteous ass who need attention and need to feel special and non-conformist so much that they don't eat animal products and they condemn anyone who eats meat.

Note: All vegetarians are definition 1, but not all are definition 2.

A diet lifestlye chosen by usually intelligent people who can see the horrors of intensive,battery, so-called "farming". Others choose it becuase they feel offended by slaughter or simply don't like meat.
Not to be confused with vegans,PETA, animal rights campaigners etc. althought they are sometimes affiliated.
Vegetarians are often laughed at by meat eaters (see moron) but,hey,I'm not the one with 6 pounds of beef rotting in my stomach.
Many vegeatarians are passionate about their respect of animals and believe in humane rights for every living creature,it does not mean they are hippies or terrorists.
Usually vegetarians are very nice,quite liberal people, who have an interest in politics,the arts and anything they fancy. They despise homophobia,racism and sexism due to their caring,slightly anarchic nature. Often they have a anti-corpration,anti-war stance.
Some people are vegetarians for the sake of being vegetarian, as it is "cool". These people are obviously quite dumb.

When someone tries to start a beef with you, you recline.

Best type of person there is, aside from vegans, who don't eat any part of animal corpses or anything derived from animals' carcasses.

People who don't eat meat or fish. To be clear : there is no such thing as a vegetarian who eats fish. That's a pescitarian.
Many vegetarians have to put up with idiots telling them that they are any and all of the following : fanatics, insane, fascist, obsessive, selfish, assholes, bullshitters...It's pathetic. If I told you that I didn't eat spinach (I don't - yeucch, spinach), would you feel compelled to sermonize on the 'fact' that I worship the People for the Ethical Treatment of Spinach society, try to force others to give up spinach, and am self-absorbed in my decision to avoid spinach? I don't think so.
People who choose to eat meat, do. Nobody stops them. Are they scared that the big bad vegetarians will come and take their steak away? And then they'll waste away to nothing because they’ve no protein? The average person in the western world consumes around 4 times the amount of protein needed, and some substitutes like soy and Quorn actually contain more protein than meat, not to mention virtually no fat.
A vegetarian is someone who has made an informed life choice not to facilitate the slaughter of innocent animals. A meat-eater is someone who, sometimes for good reasons, but sadly sometimes through ignorance and selfishness, has chosen to prioritise their own preference for meat over the suffering of the 11,000 sapient innocents that an average person eats in a lifetime. If one group should be angry with the other, then in my view, it shouldn't be the second.
