Legal crime of where anal intercourse occurs, but ejaculation is not a requirement, for the charge to be laid. Similar to Sodomy Laws.
Where anal intercourse occurs, willing or not, between a man and a man, a man and a woman, a man or woman and an animal.
Within most Common Law Countries, 'buggery' was a charge laid, whether or not the parties involved were consenting to it or not.
It was not considered a defense even if the two were married, as buggery was about the 'anal penetration' whether with a man or woman.
First appeared in English about 1330, but wasn't associated with a sexual act until around 1555.
Buggery as a crime was first noted in the English Law, the Buggery Act 1553, and later in section 61 of the Offences Against the Person Act 1861. Neither act clearly defined what was meant by 'buggery' though it was later defined to be anal sex, without ejaculation.
The term arose from the French word 'bougre' which was in reference to the Medieval reference to a sect from Bulgaria, (the Bogomils) that was opposed by a mainstream religious order, and were claimed to be practicing 'sodomy'.
To anally penetrate another person, though ejaculation was not a requirement to be charged with such a crime, under 'common law' of the time.
Mainly the practice dealt with the anal penetration, however in that matter of woman, and animals, it included contact between the woman's vagina, and the animal's sexual organs.
Practice (Associated Acts): In the Law Encyclopedia, the term also refers to a criminal charge being laid, for when a penis is inserted either into the anus OR mouth, for the purpose of copulation.
This includes either sexes, and animals.
Noteworthy: In the English language, 'bugger, buggery' are considered to be profane words, used in a derogatory sense. It still does refer to anal sex as well.
Buggery Laws have been altered in most Common Law Countries, to exclude couples that have given their consent to such a sexual act, such as two men, or a woman who has been anally penetrated.
As animals cannot be deemed to give consent, the act of sex with them can still be called 'buggery' though most have changed their laws, statutes to use alternative language.
Most notable, is 'Crimes Against Nature'.
Used to express shock, or a form of outrage over something, like even breaking a nail.
As well, used to reference a less than savory person, one of low morals, or ethics.
