A phrase that is akin to “it is true that” or “I think that”, “no cap” is often used to describe an opinionated statement or a statement that is believed to be true. Stemming from the verb capping (basically, “to lie”), it quite literally means “no lie.” Because of this, no cap can be used to describe something that is not thought to be true by the speaker’s audience. No cap can be used to describe factual statements, but due to its slang nature, it is most often used in an exclamatory manner.
