What does Nefarious mean to you?

I received an email today with this word in it. They used it to explain their intentions. While I know what it means - I decided to look it up just to see what the 'real' definition was vs. the 'amber' definition. These are my favorite I found. ** I bolded the words I liked - while keeping the definition. Just in case you would like to source the information later.

**I find it interesting that this person thinks that their plan is wicked to the extreme. It makes me smile just a little bit. Too bad I had a pretty nefarious scheme as well.
