What does it mean to "fight dirty"?
<|assistant|>
To fight dirty means to engage in unscrupulous and underhanded tactics in order to achieve a goal, often violating commonly accepted standards of behavior. This can include lying, cheating, and slandering the other person in order to gain the upper hand in an argument or competition.  In the context of a conflict, fighting dirty means that rather than raising valid points or engaging in meaningful dialogue, one side is engaging in behaviors that demean, denigrate and are designed to make the other person look foolish. It is generally considered to be an unsportsmanlike conduct, or not following the rules of the game, and often results in penalties or repercussions.
