A negative term to describe someone who consumes marijuana where such drug is clearly having a detrimental effect on their being.
Can also be taken as a play on words to say that someone was 'weeded out' (taken out) of a program/job/place etc due to their drug use.
Person 1: Hey I kind of like her, but they're kind of... dull?
Person 2: well duh, she's totally weeded out. Look at her friends, how she talks, real obvious.
when you're holding up your phone and making faces at it, as though you are taking a selfie, but you're really taking a picture of the person across from you or the wall or anything else that seems interesting but you don't want to be caught dead taking a picture of.
This action is often made more convincing by wiggling the eyebrows or opening the mouth, to pretend you're trying to get a Snapchat filter to work.
FRIEND A: "Did you just take a stealthie of me?"
FRIEND B (turning phone around): "no I was just using snapchat's new filter, see?"
