The marketing and packaging deception practiced by certain manufacturers to mislead consumers into believing their product is "green" or eco-friendly.

I noticed that my detergent package has been "greenitized" by their marketers...it now has a lush forest waterfall and green colored writing on it!

Greendian Moment 

When someone makes a very dumb mistake and doesn't realize it at all. All noobs who are pupil and newbie on Codeforces suffer from it. Sometimes it can also be observed in experts and cyans.

I could not figure out that a number having only 2 distinct factors is a prime during the contest. Now this is truly a greendian moment.
