The word 'vegetarian' has come to be used differently over the years and now often used to describe people who are not, strictly speaking, vegetarians. I used to sometimes call myself vegetarian, just for simplicity's sake. It's quicker and more accurate than saying 'I only eat fish' (actually, I have a rich and varied diet which only occasionally includes seafood). I recently found out that there's a specific term for people like me. I'm a pesco vegetarian.

Other useful terms include:

Lacto ovo vegetarian:This diet excludes meat, fish, and poultry, but includes dairy products and eggs. This describes the majority of vegetarians in the Western world.

Lacto vegetarian: excludes meat, fish, poultry, and also eggs and foods containing eggs.

Vegan: Diet excludes meat, fish, poultry, dairy products, eggs, foods made from by-products of these ingredients, and sometimes honey. Vegans also avoid animal products in other areas of their lives ie. They don't wear leather, silk or wool and avoid other items containing animal by-products or which have been tested on animals eg. Cosmetics. These guys are hard-core. I don't agree with them, but they have my greatest respect.

Semi-vegetarian: A person cutting back on their intake of meat.

Pollo vegetarian: Excludes red meat and fish but eats chicken.

Pesco pollo vegetarian: excludes red meat but eats chicken and fish.

Sometimes other people's eating habits seem very strange to me, but I try not to be judgemental about it, since mine must seem equally strange to others.
