To go rainbow on something comes from the phrase "colorful language."

It basically means swearing at someone.

I wanted to go rainbow on that asshole.

Phenomenon used to explain that douchbags come in every shape and colour. Used primarily as a new category of people to be racist towards (to combat regular racism).
