trash

Trash-talk is a form of 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 as to win easier, but it 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.
Trash-talk was most famously used by heavyweight boxing champion Muhammad Ali in the 1960s and 70s. In 1963, Ali even released a popular full-length record album consisting largely of trash-talk poetry. It was entitled I Am the Greatest!, a phrase that became his signature line. Since then, it has become common for boxers, wrestlers, and many other sports competitors to use trash-talk. However, in amateur sports ranks, trash talking is generally frowned upon as unsportsmanlike conduct (especially in youth leagues). UFC Lightweight Champion Conor McGregor is a more recent example of a prominent trash-talker, while former UFC fighter Chael Sonnen is considered by some to be the greatest trash talker in UFC history. Although the practice of trying to distract opponents by verbal abuse is common to virtually all sports, other sports sometimes have their own terminology for verbal abuse: for example, cricket calls it sledging and in ice hockey it is called chirping.
Trash-talk has become a debatable term especially in North American sports, with the greatest trash talkers being acknowledged for both their trash talking skills as much as their athletic and mental abilities.
