Ninjatext

Ninjatext is text that is the same color as the background it's on. You can only see it if you highlight it. It's really annoying.

People usually use ninjatext to say "jk" or "sarcasm" without ruining the joke.
It gets it's name because it's stealthy, like a ninja.

I was offended when that guy on that blog said he hates black people, but then I saw his ninjatext that said "Just kidding, I'm not racist."
