Bloody

Bloody is a commonly used expletive attributive (intensifier) in the British English. It was used as an intensive since at least the 1670s. Considered "respectable" until about 1750, it was heavily tabooed during c. 1750–1920, considered equivalent to heavily obscene or profane speech. Public use continued to be seen as controversial until the 1960s, but since the later 20th century, the word has become a comparatively mild expletive or intensifier.

The word is also used in the same way in Australian English, New Zealand English and in other parts of the Commonwealth or in ex-Commonwealth countries, but it is not common in American English, and seen as a stereotypical marker of British English by American audiences.
