Generalized vague or exaggerated claims particularly when asserted humorously

Generalized, vague, or exaggerated claims particularly when asserted humorously are called puffery.

Puffery is usually used in advertising, when companies try to show their products as better than they usually are. They praise them, and sometimes exaggerate a bit in order to sell their products faster.

A claim is just something you say, it doesn't have to have this definition that refers to puffery. Concatenated reasoning can either be true of false. Slanting is telling lies about something.
