convenience friend 

A person who is only around when it is easy and convenient for them. They are the people who, if not placed around us, (ex. dorm rooms), all the time, they wouldn't really be friends. They are usually used to do things for you, if you need a ride to and from school, etc. They are basically friends who need you around when they need a favor, or when they are just so bored out of their minds that they would rather hang out with you than sit around all day, but they'd never put you first.

Alice lives down the street.
You: Hey what are you doing today? Want to stop by?
Alice: Sure! I'd love to hang out.

Alice lives 10 miles away, and is sitting at home watching Judge Judy reruns all days.

You: Hey what are you doing today? Want to stop by?
Alice: Oh, no, I'm really busy. Maybe some other time.

* You don't hear from Alice again.

Elena and Becky, Becky is a convenience friend.

Elena: Hey Beck, think you can give me a ride home tomorrow?
Becky: Sure, want to hang out afterwards?
Elena: I would but I have homework to do.

Twenty minutes later, Becky sees Elena going to the movies with Maggie.

Best Friend Syndrome 

When you're really close with a member of the opposite sex and would like to date them but they refuse to date you because you are too close and they wouldn't want to make anything awkward between the two of you if the relationship didn't last.

You have best friend syndrome if...
1) You hang out with the person of your dreams more often then your friends. But ARE NOT dating.
2) They ask you to take them to an STD test or a gynecologist appointment. Or go with them as moral support to get Plan B (even though you weren't the one to have sex with her)
3) Other acts that a boy friend/girlfriend would do minus the sexual benefits, emotional attachments and etc.

Mother: So hows Andrew doing? I'm sure hes not too happy you dumped him for Josh.
Daughter: Are you kidding?! We were never dating, he just had a bad case of Best Friend Syndrome.

Fallback Friend 

The friend that your other friends don't know, who you go to when the shit hits the fan.

Jack:I'm tired of all the drama,I'm gonna hang with Chris.
Bob:Who?
Jack:Exactly.

"Dude, Where were you last weekend?"
"I was at my fallback friend's place all weekend, so I could avoid the shit thats been happening."
"Good plan."

background friend 

Someone who's friends with lots of people from different friend groups but isn't necessarily confined to one, typically an ambivert, sometimes the center of attention but also gets left out often, never asks for help, doesn't really know whats going on sometimes, and doesn't really have a best friend in their friend group since everyone has their own best friend in that friend group but copes with that by considering everyone in their friend group their best friend.

friend: Have you seen Myles? He seems pretty off today, he's really quiet today.
another friend: It's alright he's probably texting that other kid. After all he's just the background friend.

Mechanic's Friend

1. Any Vehicle of any make or model known for inherent problems.
2. A car/truck/van/etc that is broken more often than it is running.
3. Any goofy, oddball, badly engineered, or poorly implimented component that causes a vehicle to reflect definition 2.
4. That tiny 99 cent part that breaks at the most inconvenient time and then magically ballons into a $1,400 shop bill.

Dammit! My Thunderbird is a real Mechanic's friend! That's the fifth starter it's chewed up since I bought it!

Mom of the Friend Group

A friend who is like a mom, they will treat you and your friends like her kids, they will also be someone who regularly checks on you and keeps you out of trouble. They will be the one who gets you out of fights and settles them. Really good advice giver.
