ELI5: I've heard so many so called "right" and "wrong" ways we are supposed to use the word "irony". How is it actually supposed to be used and what are common ways it is used improperly?

Irony is when a situation occurs that is the opposite of what is expected. There are some other uses--like dramatic irony, which is when the audience of a movie/book/etc. know something the characters don't--but this is by far the most common use.

However, lately people have been using irony to refer to any situation they find to be mildly amusing.

An example: If you meet a prostitute who comes from a place called "Sextown", this is not ironic. It's amusing, in a certain way, but it doesn't go against your expectation based on the name.

If, on the other hand, you meet a prostitute from a place called "Chastity", this is ironic, because it goes against the expectation.
