when you pop a pill or take a hit and stare blankly into space while drooling with your mouth open because its so strong it hits you hard.
Friend: "whats wrong with him?"
Me: "he just smoked some strong. It's got homeboy insta-dumb."
When you and a friend have the same thought at the same time.
You and a homie are smokin a blunt and both of you say "damn my mouth is dry" out loud at the same time. twin teleps
