someone you are no longer friends with but not quite enemies enough for nemesis or frienemy to be the right word to describe them when people bring them up to you in conversation without using their name.
mutual friend: "I was just talking to your nemesis..."
you: "I prefer the term 'non friend', nemesis suggests I'm taking part in some active hate again them, when I honestly don't care anymore."

Any used-to-be friendlyhuman idiot who has hurt you in any way, including leaving you out, bitching behind your back, or just generally acting selfishly and not thinking you would notice.
A friend at heart, but provides sexual favors in return for a loyal friendship. A lover friend knows his/her role, understanding they are indeed a step over the line of a "fuck buddy" but not anywhere near a boyfriend or girlfriend. A lover friend cannot give or receive gifts for a holiday, birthday, or any other special occasion, but is allowed to give out free sex whenever he or she pleases. Your lover friend should not have feelings for you, and if they do they are wasting their time.
A Fake friend is someone who only talks to you when they want something. They will act like your friend while you're around but will take the first chance to snake you out.
