When you have been smoking for awhile, but then you hit something strong and strange and it gets you there quickly, there stupidly, and in the sweet spot. You know, like the first time you smoked, got high, in the eighth grade.
I went to my friend's house on Saturday to smoke out and my friend pulls out some dabs. I got that Eighth Grade High, again. You know what I'm saying?!
