De-friend

Someone you have de-friended on Facebook but still see around, in an awkward manner.

Oh, he's a de-friend... Awkward!

I pretended to be on the phone earlier when I walked past him, he's a de-friend.

I saw her out the other night, I gave her a dirty look as I'm now her de-friend.

best friend 

The friend you are closest to. No other friends are as close to a best friend as your best friend. They never leave you out, and actually care about you greatly. They are people who you tell everything to. They love, you and never call anyone else their best friend. They can also be rude, but never take it to offense. Share tons of inside jokes

You don't compare to my best friend

fake friend

A retard who never comes up to you or asks you to hang out and says that they are your friend. If your 'Friend" gives you "Advice" while really pointing out your flaws and making fun of you, they are for sure a fake friend. They also always talk about you behind your back and try to make you hated.

Person: I always have to ask someone to hang out or I have to always go up to them to start a conversation
Real friend: They sound like a fake friend, get better friends

Toxic Friend 

An absolute nightmare to have.
Friends who are toxic are often negative about everything, they talk a lot of shit behind your back, they turn your friends against you and they're generally hated by everyone. Not to mention that they don't congratulate you about ANYTHING.
A toxic friend may seem alright for the first few times but when there are other people around they won't hesitate to embarrass you.
These remorseless pieces of shit must be exterminated otherwise more and more people will suffer.

Oh my fucking god, I hate David so much! He's such a toxic friend.

as a friend 

Used to clarify the extent or limits of a relationship between two people in which one or the other wishes it to go further.

I'd prefer to keep you as a friend.
