What does "Green Out" mean?
Definition: When someone smokes too much weed and gets way too high. Roughly equivalent to blacking out, except with weed instead of liquor. Most often the person who has greened out will become very quiet. In some situations, they may even vomit. If it’s bad enough, the person who has greened out might fall asleep and wake up high the next day. Generally not a good experience, though it does wear off after a while.
Example usage for Green Out
“Yeah, I can't believe Maureen Dowd greened out and then wrote an article in the New York Times about how weed is dangerous. If I had never had a drink in my entire life and then one day I downed half a bottle of tequila, would it be my fault or the tequila's?”
