<human>: Could you distill the essence of the text into 1-3 sentences?

**Back story:** So I got a brother, who's a huge jerk. He's a constant dick to everyone in the house and will always pick on me if he gets the chance. He'll even yell and beat my parents if he doesn't get his way.

So yesterday, I got the new Smash Bros game and I decided to wait until Friday to play it, so I hid it in my room so my brother wouldn't find it and sell it without telling me. I really wanted to make Friday a great day, but my brother will be here on Friday, so I made him an offer. I told him that I'd give him $50 if he leaves on Friday morning, and comes back on Saturday. He told me that I he'd do it for $100 and I told him that I'd think about it. I thought about it overnight and I decided that $100 is too much so I was gonna leave the thing and just let him stay.

This brings us to today, I tell him the deals off. Instead of what I thought would happen, he told me that he'd bring his meanest, cruelest gang member friends over on Friday and let them stay there overnight in hopes that I'd give in and give him the $100. 

Great, I fucked up, again.

These guys literally had videos on Facebook of them running after fat kids and making them cry (remember these guys are 18-20). And me, being my 25 pound overweight self, got really terrified. My parents know about their gang affiliations and told me that they'll make sure they won't come, but I'm sure that they will. What's gonna happen now? Guess I'll find out on Friday just to piss me off.
<bot>: Told my brother to leave for a day for money, decided it wasn't worth it and let him stay, now he's gonna bring his gang member friends on Friday.
