'Trash talking' is a commonly used tactic in internet forums whereby said 'trash-talker' openly insults or abuses another person or brings up previous disputes to depose their argumental position. Trash talking is a form of trolling with the aim to illicit a similar response from the targeted person or to derail the original discussion.
A discussion about how to change the rules of a game on a forum is several pages long, trash-talker interjects with 'hey you, fucktard, you can't say anything because you take it up the butt and we all know it'. Target has just the victim of a Trash Talking attempt.
