One of the two genders of all living things, the other being male. Females are physically indentifiable by their sexual organs which differ from a male's (well it's true I'm not being crude on purpose), a female having a vagina and breasts, the latter not being developed until puberty around the early to late teens.
A typical (I said typical!) female will have long hair and softer, more feminine features than a male, and wear more aesthetically pleasing clothing, getting away with colours such as pink or lilac which a male will more than likely get slated for wearing.
A female of any species has the job of giving birth and caring for offspring, except seahorses; the female lays the eggs, the males fertilises them and then carries the fertilised eggs until they develop into baby seahorses and are 'born'. However the 'non-politically correct' job of human females is not only to produce and care for offspring, but not work and stay at home to cook and clean and care for the house. They must also remain faithful to their husband and care for and obey him. But in the last few decades, feminists have become more prominent in society: mainly females but also males intent on getting equal rights for men and women. Sadly in doing so some (not all!) of these feminists, usually the women, have become sexist themselves and slate men at every given opportunity. But if you want to hear more about that then look up male in urban dictionary.
In truth the only differences and inequalities between males and females are the physical ones; general appearance, reproductive organs and stereotypical style. Men and women both have mood swings and hormones. They both can be violent and bad tempered. They both are capable of sleeping around. They both have the capacity to cheat on their significant other or treat them badly. They can both be immature. They both are able to be sexist, racist, prejudiced, unfair, corrupt, discriminating and every other awful thing you can think of. But they can also both be the most beautiful, intelligent, loving, caring, generous and fair people on this earth, if only they'd let go of their unjust ideas and realise: we only live once. There are no second chances. We should be celebrating life, not ending it; we should appreciate every second we are with our loved ones, not abuse them and their trust; we should be making friends with everyone possible, not making enemies with everyone they don't like the look of.
But this is not a rant, it is a definition. If you wanted that, look at the example.

Most definately the finest thing ever created

1. A girl
2. Not of the male gender

Other words relating to the human species are woman, girl, lady etc.
Clearly there are some men on here have some kind of weird problem with women, shown by the warped and generally psychologically imbalanced statements below.
I'd just like to say I have nothing against men at all before I start addressing what has been said.

1. I know all that crap some guy wrote below about being female is a birth defect is just some kind of bitter, irrational and unfounded metaphor but I might as well address it as if it were meant truthfully. Let me point out that all embryos start off as female, and it is actually the Y chromosone that later on turns any male babies male that could be perceived as a 'defect' (even though in reality neither are), as it is only half the size of the second X chromosone of its female counterparts, and it is the cause of haemophilia in males as they can be missing the blood clotting gene in the missing part of the chromosone, whilst females cannot get this condition as they have two full XX chromosones.

2. One of the disturbed individuals below said that women are less intelligent due to having smaller brains than men. Well, if you did any kind of science you would know that in humans brain size is not related to intelligence, men merely have bigger brains as their bodies are proportionately larger. This has also been shown by the fact that sufferers of the condition microencephaly (a condition where the patient's brain is far smaller than normal)...

lucky bastards who get more and better orgasms than men!

1)n.- The opposite of male in any species on earth, usually the reproductive member of the species, except in seahorses, coming in a variety of classes from cherished partner to ankle.
2)n.- The only match to the male human that constitutes a heterosexual relationship,

Meaning no or without nuts. Not wanting nuts on something.

A person containing the XX pair of chromosomes, and as a result tends to be gendered into a motherly, ornament-like identity, with masochistic tendencies as she is encouraged to disfigure/mutulate her body.
