When one wants to do someone else really badly. Usually, one wants to fuck lots of people, but there are exceptions.

You know when somehow has fucking fever when:
-They talk about sex a lot.
-They talk about sexing up lots of people a lot.
-They say Dr. Phil is hot.
-They express enthusiasm whenever something sexual is mentioned.

Is there a cure to this madness?
Simple answer: Not a definite one. The best thing you could do is find your friend/person who has fucking fever a partner/hot guy/hot girl and let them do each other. ...Or, you could try to tell them that sex is a natural part of life and there's nothing to giggle about when the word "penis" is mentioned. Or, you could restrain yourself from getting sexual for the rest of your life. It's your choice, really.
