"Never wrestle with a pig, Lindsay. You both get dirty" is a quote from James Patterson's book 1st to Die. It suggests that engaging in a pointless or messy conflict with someone who enjoys chaos can be unproductive and only lead to trouble. The phrase emphasizes the importance of avoiding unnecessary struggles with individuals who thrive on conflict.

The quote serves as a metaphor, warning people to choose their battles wisely. It highlights the idea that some opponents or situations are better left alone, especially when they are inherently disruptive or manipulative, to prevent oneself from becoming involved in unnecessary mess or negativity.
