Trash talk

Form of boast or insult commonly heard in competitive situations

Trash talk is a form of spoken insult usually found in sports events, although it is not exclusive to sports or similarly characterized events. It is often used to intimidate the opposition and/or make them less confident in their abilities to win easier, but it can also be used in a humorous spirit. Trash-talk is often characterized by the 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.
