Greenday

A common misspelling of the name of the band Green Day.

It's "Green Day," not "Greenday."

Greene 

See gay as all hell. Greene references to a male that likes to lick other males unwipe dirty inches. You may also suffer from a tendency to munch on fecal matter whilst jerking-off. Greenes are often recognized by their bad breath and shit-stained teeth. You may want to avoid them at all costs, unless Greenes float your boat.

That guys breath smells like shit, he must have Greened some dude.

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.

Greener

Someone who attends the Evergreen State College in Olympia, WA.

A stereotypical greener will have dreads, dress like a homeless person, smell like a wet dog who just smoked a pack of clove cigarettes, and live off of their mommies and daddies. In reality most greeners are very nice, clean, upstanding members of the community, their reputations are just sullied by the dirty hippies who are majoring in pottery.

Girl: "What's the quickest way to starve a greener?"
Guy:"I don't know."
Girl:"Hide their mom's credit card under a bar of soap."
