Frientor 

A contraction of the words friend and mentor.
Friend - Person with whom time spent is mutually enjoyed.
Mentor - Person who can teach and, more importantly, inspire and motivate you.
A person who is both would be a frientor.

Lewis enjoys spending time with Rudy. Rudy is a couple of years older than Lewis, and can teach him things, while having a good time, because they have similar interests. This also causes Lewis to want to be better at the things that interest them both, in order to both impress and be more equal to Rudy in both confidence and expertise. Rudy is Lewis' frientor

Frientropy 

The natural tendency of relationships to disintegrate. Based on the concept of entropy in nature, this phenomenon can be measured by considering factors related to the compatibility and mental integrity of friends.

Rita has a extremely high rate of frientropy because she is a jealous, back-stabbing bitch, whereas Nancy's frientropy rate is rather low because she has a magnetic personality and is nice to everyone.

Friendor

A word used by event vendors (professionals) to refer to other event vendors that they've developed friendships with.

Contraction of the words "friend" and "vendor".

First known use of the word was in 2007 by Famous William Company.

I worked with that wedding planner 4 weddings in a row, invited her out for mimosas and networking, and now she's my favorite Friendor.

I'm planning a styled shoot and inviting my Friendors to collaborate.

I have a tight circle of Friendors that I refer my brides to.

Friendtor 

A friend who is a mentor

Is there such a thing as a friend who can also act as a mentor? Sure! That's what I'd call a friendtor.

frientourage 

The aggregate of family members, friends, friends-of-friends, classmates, co-workers, admirers, etc.--and any combination thereof, past and present--who have become your friend or contact on a social networking site (e.g. facebook, twitter, or MySpace), then follow and comment on your daily activities.

Jason: So I got pretty hammered at the bar last Friday. Photographic evidence was posted and tagged on facebook this morning. Chris: Uh-oh. What has the rest of the frientourage said about it?
Jason: Those who know me IRL didn't have much to say--they've seen it before. A guy I worked with at my last job wants me to invite him along next time. The worst part was my aunt, who saw the pics and told my mom. Mom called all worried and asked if I had "a problem".
