<human>: Can you provide a brief rundown of the text in within 3 sentences?

So this all actually started on Christmas. My mom got one of my brothers a branding iron for Christmas with an M on it. (M is our last initial) They also got me a Go Pro. Last night we had a small party, nothing to crazy just a few friends over that we hadn't seen in a while. 
After a beer or seven, my three brothers decided to use the M to brand themselves. I sneakily got the rubbing alcohol, claiming it was for a cat scratch that one of our friends received. After our parents went to bed the boys made a small fire and heated the branding iron. Obviously, I got my Go Pro out and filmed the whole thing. One by one they branded an M on to each of their left arms. We all joked about my parents reaction. We knew they wouldn't approve, but none of us guessed just how much. I mean they bought him a branding iron as a stocking stuffer. They knew what was coming, right? 
We expected a "y'all are fucking stupid, keep it cleaned" and nothing more. This morning at breakfast my dad came in and said we left the rubbing alcohol outside and asked why it was our there. My mom, assuming I'm not a filthy liar, began to tell him that one of our friends was scratched by my cat. Most of our friends crashed at our house last night so when my mom started up with the cat story everyone started giggling. One of my brothers decided to show our parents, who then proceeded to get pissed the fuck off. After some yelling at the brother that showed them his M brand on his arm, the other two decided to keep quiet. (We're all in our early 20's and none of us will be home for long anyways) My mom is currently not speaking to any of us and telling her dog that she is her only child now.
<bot>: My mom gave my brother a branding iron as a stocking stuffer and then got pissed when he branded himself. Little does she know her other two sons did it as well. Today my mom fucked up.
