I apologize for misunderstanding your initial question.

The idiom "mess with someone" typically means to bother, annoy, or tease someone in a playful or sometimes hostile way. It can also mean to interfere with someone or something in a way that causes disruption or chaos.

For example:

• "Don't mess with me, I'm not in the mood for your jokes today."
• "I wouldn't mess with that machine if I were you, it's not working properly."
• "He's always messing with his little sister, but she knows how to stand up for herself."
