friendicide 

The merciful act of helping a friend end his own pathetic existence.

You and your friend work together selling cars in Wisconsin in the middle of the winter. You are stuck at the dealership for long miserable hours with no traffic and nothing to do. "Dude, I fucking hate my life, you think you could do me a solid and commit friendicide on my sorry ass"?

Friendicide 

To help eradicate a friend under false pretenses because of an intentionally skewed perception of them.

That J. E. Was a victim of Friendicide due to believing a bunch of psychological mumbo jumbo meant to cater to they're desires but actually to make them complicit in a murder while being entrapped by law enforcement.

Friendcierge 

A Friendcierge is that great friend who will advise you on everything. Where to go, what to do, what to buy, what's hot and not, what's cool and not so cool. They wil gladly provide solid advice on just about everything and you value their opinion. A great friend with great advice.

So i called my Friendcierge and she advised me to buy expensive designer shoes, which I couldn't afford. Years later, I'm still wearing and loving them. They were worth every penny! Great Advice from a Great Friend.

Friendcidence

when two of your facebook friends from totally unrelated social circles somehow become friends.

I knew Lori from school and I dated Lisa. It was a total Friendcidence that they added each other on facebook.
