look up any word, like donkey punch:
This is a term coined by a good friend in my band. He made this word up and then started hearing it all over the state, no joke!

it is simply put, "a flaming anus" like when you have to put on a hard hat and a rope for climbing just to hit the pottie.

devilish and wicked.
You are such a flanus.

I can't believe that yer flanus has been acting up for the last 5 hours!
