Green Day 

Punk Rock band which regularly produces hit albums, upon each of which their old fans proudly pronounce Green Day "sellouts" and proclaim that their new fans are posers and wannabe punks, blissfully ignorant to the fact that they were pronounced the same by even earlier fans a few years back.

Ten years ago:
"Green Day used to be punk back when they did Kerplunk, before they sold out with Dookie."
Today:
"Green Day used to be punk back when they did Nimrod, before they sold out with American Idiot."

Green Pill

Describing having taken on an ideology and/or lifestyle concerning enviromentalism and conservation of the planet, usually in terms of addressing global warming and climate change.

The Green Pill can theoretically be taken with other pills, since ignorance, knowledge, hope and despair (blue, red, white and black respectively) are states of being that might exist alongside a belief in earth's need for preservation and saving.

Tabitha: "Did I tell you my dad got totally Green Pilled? He finally did some research and he's stopped buying water bottles and bought a bike!"

James: "We aren't going to know global warming is real until it's too late. We are frogs being slowly boiled in a pot."
Jeff: "Yo, the ol' Green Pill Black Pill combo, eh? I'm meeting a lot of those lately."

green day 

Green Day is the name of the now band formerly known as Sweet Children, from Rodeo Cali. The members were potheads as teenagers and were watching Sesame Street once, and they said 'green day' at some point on it and they thought it was funny. So, it became slang for day spent smoking marijuana. John Kiftmeyer (aka Al Sobronte, former drummer of Green Day) had a jacket made that had 'green day' written on the back, and eventually they decided to make it their band name. They also have a song called 'Green Day' that is pretty much about the same thing.
Also, the best band in the world, btw.

'at green day yesterday was awwwwwwsome. the teletubbies are so friggin funny!

green ninja 

The untmost elite of newbies. The omninoob. Probably grew up really sheltered. One lacking in common sense or culture to the degree that he/she could be classified as being "skilled like ninja" at being a greenhorn. The proverbial 40-year-old virgin.

You don't know how to pump gas? You've never heard of Bruce Campbell? You've never played spin the bottle?? You're such a green ninja!
