In sports, trash-talk most commonly comes in the form of insults to an opposing player's playing ability or physical appearance which is ethically not acceptable.
In 1963, Ali even released a popular full-length record album consisting largely of trash-talk poetry.

One of the earliest references can be found in Dobie Gray's hit song from 1965, "The 'In' Crowd," in which the third verse describes members "spendin' cash, talkin' trash" as part of the depiction of a desirable group membership.
