Why are they called Green Day?
The phrase “green day” is Bay-area slang for a day with lots of green bud where you just sit around taking bong hits, hanging around. Billie Joe picked the phrase up from friends while chilling in his “habitat” (in the basement of a Berkeley University building), and wrote the song Green Day about his first pot experience. The group changed their name from Sweet Children to Green Day in 1990. Note too that Ernie from Sesame Street has also uttered the phrase Green Day (Ernie also appears on Dookie… coincidence?).
