Greechies 

When you get extremely excited for an event you are looking forward to as an adult, and your body tenses up to the point where you can't talk or move correctly.

As we sat and planned for the party at the lake with my friends, I got the greechies and couldn't talk or move for a few seconds.

2 Greenies for a Blackie 

The art of skillfully gesturing someone to roll down their car window at a stop light after witnessing them successfully pick their nose and eating it, by a using hand cranking gesture. When they roll their window down ask them if they would be willing to trade you "2 greenies (2-GREEN colored boogers) for a blackie." (a BLACK colored booger)

A) Letting them know you actually watched them the whole time, while they excavated around in their nose for their boogers & then ate them.

B) Embarrassing the fuck out of the nasty bastard for subjecting you to having witness that disgusting act they performed while in traffic, at that stop light.

C) Hopefully reminding them in not so many(unspoken)words, other than what you already said to them- it's a filthy habit that they should have given up as a small child.

"Hey dude that looked pretty tasty, and I didn't have my lunch yet. Yours look way
better than mine, bummer. Next time I'll trade you 2 greenies for a blackie."

greeblies 

In the Lego online community, greeblies are the intricate details on the sides of spaceships and sci-fi MOCs that define the mechanics and workings of what the MOC is meant to be. They were famously used in the giant Star Destroyer Lego set a few years ago, and also in the more recent Death Star II set. Plates with rails are often used for greeblies because they have a protrusion that only sticks out half a stud without needing a jumper plate. (source: Brickspace.org)

Hey, that Star Destroyer has great Greeblies.

greenies 

When alcohol and marijuana are consumed together, and the consumer gets really sick (pale, clamy, puking)

We made that guy down 4 beers after he toked 2 bowls, and he got the worst greenies ever!

greensies 

The first hit of a freshly packed bowl. Someone will call out "greensies", thus staking their claim to the first rip.

"check out this fat bowl"

"...GREENSIES!"
