Compressionist 

A compressionist is someone who has moved beyond being a hobbyist in the art of video compression, i.e. people who compress entire movies into tiny MP4s.

I actually blame Imgur's MP4 expansion for it.
Compressionists went into overdrive when it became a thing.

Compassionist 

Someone who continually strives to unite in love and grace instead of divide in anger and hostility. A person who regards feelings above anything else and seeks to soothe away pain and negativity so that the world can unite as ONE BIG FAMILY!

Great spiritual leaders are usually Compassionists. Only a great Compassionist can truly understand the plight of the less fortunate or even the sadness that dwells in the hearts that choose to hate.

Person #2: "They might be going through a tough time or something. Maybe they have a mental illness and their family doesn't know where they are."
Person #1:"Wow, thanks, compassionista! You just made me sound like a douche."
Person #2: (silence is golden)
