Memeloader 

Based off of a freeloader, memeloaders are people who do not contribute to meme making. There is typically one person in every group chat who continually demands for memes who doesn't contribute anything.

Memeloaders also tend to steal those memes to boost their internet street cred.

Chris had enough of Brandon's constant demands for memes in the messenger chat. He was being a real memeloader.
