I don't mess with 

A polite way of saying that you don't have, and don't want to have, anything to do with someone or something.

I don't mess with Matt Lauer or the Today Show ... and that's a very nice way for me to put it!

I want to say one thing to the American people. I want you to listen to me. I'm going to say this again: I don't mess with that woman.

Josh:* waves at Emma*
Alex: Are you flirting with my man? Don't mess with my man bitch.

i know karate, i know kung fu, you mess with me, i mess with you!

I think I'm cool and I totally pwn you so don't mess with me!

One might say "i know karate, i know kung fu, you mess with me, i mess with you!" To ward off unwanted attention from bullies. Mostly unsessful.
Also, a phrase used often by geeks trying to sound cool.
