Usage
What is taboo? Taboo describes an activity or behavior that is considered completely unacceptable or forbidden. A taboo is also the prohibition from engaging in such an activity or behavior through social rules, laws, religious doctrine, and even by your own conscience. Something considered taboo is considered unacceptable by the vast majority of a person’s social group. Often, there is a serious punishment for performing the taboo activity. Many activities that we refer to as crimes are examples of taboos, such as theft, murder, and kidnapping. These activities are considered unacceptable by the government or the law and have strict punishments. Sacred religious writings also outline specific activities as taboo and shouldn’t be done by the religion’s followers. For example, Jewish law considers pork to be taboo, so many Jewish people do not eat pork. Sometimes, taboos are so unacceptable to a society that laws are not needed to forbid people from doing them. Even thinking about them or reading about them can make you feel disgusted, which gives you an idea of how powerful the label of taboo can be.

Etymology
Origin of taboo
First recorded in 1770–80; from Tongan tabu “forbidden, prohibited”; the spellings tabu and taboo both appear in Captain James Cook's journal in 1777
Explanation
Something considered taboo is naughty, something society considers a no-no. For example, it is taboo to ask people how much money they earn. Taboo is one of those rare words in the English language that doesn't have Greek or Latin or French roots, coming instead from the South Pacific Islands in the eighteenth century via the explorer Captain Cook. For many islanders some things were tabu, meaning not only could they not be done but they could not be talked about either for risk of offending the Gods. This latter meaning still applies today (minus the spiritual underpinning), when we say that certain subjects are "taboo," meaning off-limits for discussion.
