What does 'I swear to God' mean?

Answer 1

IT means you are fat

Answer 2

The term "swear words" comes from the same source as the verb "to swear" (to affirm, vow, or give an oath) but it has an entirely different meaning.

A swear word is an offensive word or name that is considered very bad manners to use. It can be an insult or an exclamation. It can be a noun, a verb, or an adjective, but it's a word that people may take offense to hearing. It is the opposite of correct, civil dialogue. When a person swears, he is considered uneducated and extremely impolite.

As this type of word frequently involves the names of deities, it can also be called an oath. Again, this is not the same as an affirmation or vow.

These words are more often found (and tolerated) in modern films, especially in Europe and the US. But they may be censored (cut, bleeped, or dubbed) when the audience is expected to include minors or others who might easily be offended by the language.

Answer 3

It is a collection of word(s) that have a bad connotation in a select society. i.e. if you say that word(s) the people around you will look down at you. Most swear words have a background story that makes them unwanted in that society.

Answer 4

It means the person has not read the Christian's Bible or as much as he claims. Christians are specifically prohibited from swearing to god.
Matthew 5:34-37 New International Version (NIV)

34 But I tell you, do not swear an oath at all: either by heaven, for it is God’s throne;35 or by the earth, for it is his footstool; or by Jerusalem, for it is the city of the Great King. 36 And do not swear by your head, for you cannot make even one hair white or black. 37 All you need to say is simply ‘Yes’ or ‘No’; anything beyond this comes from the evil one.

Answer 5

Comes from swearing on The Bible in court. Someone is trying to convince another he is truthful.

Answer 6

If you swear to someone, you make a vow.
