Trash-talk
Trash-talk is a form of boast or insult commonly heard in competitive situations (such as sports events and multiplayer video games). It is often used to intimidate the opposition, but can also be used in a humorous spirit. Trash-talk is often characterized by use of hyperbole or figurative language, such as, "Your team can't run! You run like honey on ice!" Puns and other wordplay are commonly used.
