Poser Poster 

People who reshare your facebook post but did not acknowledge it by liking it

I have a friend, he is a poser poster. He keeps resharing my posts on Facebook because they are good but has never "Liked" it out of decent courtesy.

power poster 

a poster that can post around the clock at multiple online forums.

a power poster usually is getting paid by the forum owners or they just simply love to post.

some "successful" power posters became professional posters.

I can make 30 posts at 10 different forum while watching Shaq missing three consecutive free throws, I am a power poster.

Zefron Poster 

A zefron poster makes a boss horcrux in AVPM. It is also one Harry Potter, Ron Weasly, Dumbledore and one Draco Malfoy's favorite chistmatic humanitaian. It is deeply rivaled by umbridges talor launtner poster.

Ron: THAT IS A BOSS ZEFRON POSTER!
and....
Dumby: He just seems like such a chistmatic humanitaian
and....
Ron: Let's take this bit of garbage down! (atempts to take Talor Launtner)

This kind of poster has been repeatedly parodied and it's a common meme along imageboards.

I lol'd so hard with this Motivational Poster

Serial Poster

A "Serial Poster" is typically a Facebook addict and a narcissist who compulsively will add a new post about their self every hour or less. This is for the purpose of validating their own importance to a dwindling audience who is increasingly censoring them as their enthusiasm fades away with each new self absorbed post. The Serial Poster also will have a core group 3-6 unconditional fans who will "Like" indiscriminately each post that is made regardless of it's pertinence or relevance to their own opinions.

Everyone is sick of your self absorbed posts, you have become a serial poster.

poster friends 

1. Fake friends - act like they care, they don't.
You might have some stuff in common and talk them, but only because there is no one else to talk to. Once someone better comes along you'll leave your poster friends behind because after all, they weren't your friends to begin with.
2. Like a poster, you'll been seen with them in a picture but their not actually there for you when you need them.
3. Someone your seen with but they don't mean anything to you.

"I only eat lunch with my poster friends because I havn't found where I fit in yet."

Poster Child

A person who is an example of something.

Though Jerry was reckless, he somehow always prevailed due to dumb luck. When they say "Fortune favours the foolish", Jerry was the poster child.
