The Green Gas Goblin

The green gas goblin, aka Unvoicedzoo is a deformed fatass that sneaks into peoples attics and farts green gas. He tries to get pay back from everyone that said to him he farts green gas and how he doesn’t shower. Watch out for him, his farts can kill anyone in a second. The only way for him to disappear is if you say, thats not funny

Yo the green gas goblin is back!
What?
LOOK BEHIND YOU
What you mean- A

greengasm 

The warm and fuzzy feeling one gets after becoming ecologically enlightened; usually induced by listening to a ruddy south-westerner talk about off-the-grid construction, having an Australian permaculturist walking you through a food forest, or watching a Discovery Channel film about nature.

This is usually coupled with a gereric environmental-personal-responsibility lecture on the come-down when given by ecologically inclined scientists, often mistaken for global warming rhetoric by the less educated.

"I just had a greengasm after learning how to build an earthship from Dennis Weaver! It was great until he made me think about global warming..."

"That Audi commercial is like green-rape; I think I had a dirty greengasm after watching it. I have to go shower now."

"Geoff Lawton gave me multiple greengasms. I can't wait to watch that one again!"
