To get high on marijuana.
I was blasting my mind all day today.
To smoke a cigarette/blunt/or any substance that will alter your state of mind, typically to improve your ability to complete an otherwise boring task. Typically something you would say prior to doing so. Basically the equivalent of "I'm going to excuse myself real quick to go out back/run to my car to smoke a cig/blunt/joint"
i.e. Go take a smoke break
Hey man can you watch the grill? Imma go get my mind right
Im gonna start cleaning up my station, just let me go get my mind right first
I am fucking losing it over here...
Hym "In case you were wondering, I'm losing my mind over here... These fucking bastards man... Can't fucking sleep... GodDamnit...m"
Like an internet browser... 20 tabs are open, 5 of them froze and i don't know where the music is coming from.
