I was 13, on an island with a bunch of 18 year old dudes with 40s and assorted other alcoholic beverages.  So they start by playing edward 40-hands, I'm included but I only get regular beers, reasonable since I was 13, but I was still not happy.  So when one dude bitched out, I finished his one 40 for him, needless to say, I was fucked at that point.  He decided that would be a good time to tell me his life story.  Cool bro, really wanted to know your life story.  But I liked the dude so I didn't really mind, plus I was blasted so I didn't really give a shit what I was doing.  (This is all in the woods on an island...)  So we get back to the house we were sleeping in, and they decide "yo, we should smoke a bowl!"  Of course I'm like "fuck yeah!".   I had never smoked before that point, and I took like, 8 full on hits of this bowl.  Shit was I blazed and drunk as fuck.  So seeing as this was the second time I had ever drank in quantity, and smoked a fat ass bowl, I was sooooo fucked beyond belief.  I ended up in the living room of the house somehow, sitting up against a wall, banging my head into said wall, and saying ow repeatedly, while subsequently rubbing the dude sitting next to me's leg.  I feel like that can't be all that I did that night, but that's all I remember, actually, then I went to bed, and puked into a bowl... like a lot of puke.  They told me the next morning that the dude that took the bowl away walked into the other room and said "Hot soup anyone?"  Fuck yeah.  I woke up like 8 hours later with my dad drunk as fuck passed out in the same bed as me.
TLDR: Got drunk/blazed for the first time, ended up rubbing a dudes leg and banging my head into a wall, woke up next to my dad passed out in the same bed as me.
