When someone has a goatee or facial hair growth that approximates the hairy area around the anus.
Why do so many professional baseball players grow goatees that give them a fanus?

Someone who doesn't care about girls. He just goes from one to another and tells each and every one of them he loves them when he really doesn't. A player.
That Fanus only wants in a girls pants and then on to the next.

Fire Anus; from to much spicy foods. The feeling your anus gets when you eat or drink things that burn when they come out.
I went to work with a mad case of fanus from to much chicken wings and beer the night before.

Sometimes you realize you have a big day at work and you need to lay off the hot wings because you can't deal with the fanus.
