Someone who reproduces at least once, and appears to have no concept of how to raise a child.
Breeders often have skewed reasoning (or no reasoning) behind their decision to give birth, such as:

"Why did I have kids? Well...that's just what you do, isn't it? You can't not have kids..."
-
"I didn't want kids, but he/she said that if we didn't have any, he/she would leave me, so I had to really."
-
"It sorts out all the problems in your relationship! No, really!"
-
"My parents wanted grandchildren."
-
"If you have kids, you get a free house and allowance from the tax-payers!"
-
"The bible says so."

Breeders are easily spotted by the following:

- their determination to ignore the havoc wreaked by their snotty brat

- the tendancy to change nappies on restaurant tables and other inappropriate places

- their complete and utter outrage when someone asks them to prevent their child from misbehaving

- their cries of "he/she's just a chyyyuld" if you refuse to comply with their ickle precious's every whim

- their often unkept appearance, the stains of baby-food on their t-shirts, greasy skin because they didn't have time to shower between popping out to buy their fags and dropping their brat off at his dad's council flat.

This term is often associated with the childfree, though it is sometimes used by others. It is not used to describe those who do a decent job of raising their kids.

Most often used in the derogatory to describe people that elect the suburban middle class lifestyle because they are so inept the only possible way they can contribute anything to society is to produce offspring. Typical cycle goes as follows: schooling -> job -> marriage -> children -> death. Their children also tend to grow up to become breeders and the cycle continues. True "breeders" can be compared to animals such as rabbits or cattle that do nothing but multiply by breeding. The term probably got its start in the GLBT community but has since gained outside popularity.

1. derogatory term to describe heterosexuals, usually when engaged in an extended relationship (eg. marriage) with a partner of the opposite sex.

1. People who feel it is their need to pop out as many children as they can, even if they don't have the money to do so. People who actually work for a living are generally the ones who pay for their little sprogs. They also try to claim that it is selfish to NOT want children! Needless to say, they are not very bright.

2. They are usually pro-life people.

n. pejorative term for a heterosexual person, especially one who lives in a "traditional" relationship with children or who aspires to do so in the future

A heterosexual. A carbon footprint enhancer. That group of humans most responsible for global warming, deforestation and a depletion of the ozone layer. A propagator.

A heterosexual person. Formerly, this was an insult used by the gay community; it is now mostly used by straight people in a lighthearted vein to (mistakenly) show that they are down with gays and familiar with the culture.
