1. Feeling seedy in the head and or in the stomach from smoking weed.

Face goes green and the person feels like throwing up.

2.When your not getting stoned but you keep smoking and you just feel sick (sore muscles, seedy and drained in the head).

3.When one bong blows you out to sleep cause you haven't smoked in a while.

Usually happens when: A person can't finish a cone 'cause it hits them too hard and their oversmashed instantly. At this point it can become a whiteout.
Every party that bitch would try smokin' with us, but she would just GREEN OUT, even spewed all over my mans bed.

A "green out" may occur after a intake of cannabis, typically a green out begins with the person feeling like they are loosing a grip of reality following by possible vomiting amd eventual paralysis leading to a deep sleep. however if one goes through all stages but yet maintaines consciousness and does not fall asleep that does not count as a green out. People whom go through the process of a green out and do not fall asleep are true sick cunts as most people do not have the fighting will to overcome a green out once it is initiated.
yeh mate you was full fucked off those cones last night but you didn't fall asleep so you technically didn't green out haha sick cunttttt
