Colourful ( American spelling colorful)
Obviously this word means full of colour, but it can have
another, entirely different meaning.
When we use it with language, it means crude, dirty, foul and inappropriate.
Examples

ex-husband.

colourful language.
Recently, television has allowed more and more colourful
language.
