greenin out 

When a person smokes way too much marijuana and as a result, feel extremely nauseated, flushed and or chilled, and may even throw up.
Basically, it feels alot like the flu just walked up and punched you in the gut, the best thing to do is lie down, and even sleep if possible.

Me on the bus ride home last Friday. You do NOT want to be greenin out when you're in a vehicle.

Greening Out 

After smoking (normally Marajuana) you may experience greening out.

Greening out basically is when you smoke and get really sick. Normally it comes with dizziness, impaired vision and balance, passing out, nausea, or in some extreme cases vomiting. You may also become sober extremely quick. Sometimes you may also experience chills and cold sweats. Normally, in most cases, it happens with non-smokers who are doing it for the first time.

Person 1: "Man I just took a fat ass dab and now I feel sick."
Person 2: "Bro your greening out, fuck!"

Greening Out 

Makes you feel like shit for the whole night;

Makes you pray to god that you'll never smoke weed again,

Makes you say sorry to the person taking care of you, because you know in your head you just sobered them up & ruined their night,

Makes you feel like you're falling into quick sand, and your hand movements seem amaizing.

Makes you question if you've fried your brain, and this will never go away, and you'll live like a vegetable for the rest of your life.

J:"Yo man yo man yo man I think I'm greening out"
M:"No no no!"

greening out 

Involves constant throwing up and feeling extreme nausea and dizzyness for the rest of the night, possibly with continued vomiting later on. In more extreme cases, the person in question may experience hallucinations.

Occurs when someone smokes a lot of marijuana in a short period of time. Common amongst those who want to prove their masculinity somehow by smoking large amounts, usually through peer pressure.

Usually ruins the night for everyone else, as it means they must look after them and take them home. So people who green out often aren't very popular with the rest of the dope heads.

Person 1 : "Wheres he going? Oh no, he's greening out."
Person 2 : "For fucks sake, not again."

Greening out 

It makes you feel like everything is so smooth and in like slow motion and like you can feel your heart beat in like weird spots and you kinda start shaking because your head makes you think other things and you go into panic mode the best way to try and feel better is going to sleep but be careful because if you throw up you don not want to drowned in your own puke just drink most fluids mostly water and Gatorade. Take this very seriously you can make your self hear things and see things and you think it’s real just you gotta be watched by someone and after throwing up you feel normal again this is the second time happing to me I smoked last night when all this happened and I still woke up high my eyes were still blood shot and I still felt the same but I have just slept the whole day just be very careful this is caused by smoking to much weed

All the time smoker: here try this
New smoker: I like this ima keep hiting it
All the time smoker: feel weird ?
New smoker: yeah everything is moving I’m gonna puke n I hear things

All the time smoker: that’s normal you just smoked to much it’s called greening out

Greening out 

When you smoke so much weed that those little thoughts in the back of your head that are kind of anxiety inducing come straight to the front of your head like a goddamn bus like it'll have you be in paranoid of every little thing or you'll get so high that you don't feel well or you'll get so faded that you just pass the fuck out

Ex: yo, I took way too many hits off the pipe bro. I don't feel very good I think I'm greening out *passes out*
