A teen gang in South London defend their block from an alien invasion.

Sam: What's Ron's weed room?
Brewis: It's a big room! Full of weed. And it's Ron's.
Pest: They arrest us for nothing anyway.
Moses: No, I reckon yeah, I reckon, the Feds sent them anyway. Government probably bred those things to kill black boys. First they sent in drugs, then they sent guns and now they're sending monsters in to kill us. They don't care man. We ain't killing each other fast enough. So they decided to speed up the process.
Pest: Believe!
Ron: [about the alien the boys found] No idea. Not a bloody clue. Maybe there was a party at the zoo, and a monkey fucked a fish.
[of the first alien the boys killed]
Ron: It smells like a shit did a shit.
Moses: Allow it.
Pest: You're quite fit you know? Have you got a boyfriend?
Sam: Yeah.
Pest: You sure about him? Where is he? Cos he ain't exactly lookin' out for you tonight.
Sam: He's in Ghana.
Pest: You going out with an African then?
Sam: No... he... he's helping children. Volunteers for the Red Cross.
Pest: Oh... is it? Why can't he help children in Britain? Not exotic enough is it? Don't get a nice suntan. Tsst.
Pest: I'm shitting myself innit', but at the same time...
Moses: What?
Pest: This is sick.
[the boys, running from an alien, have followed Sam into her apartment. She runs into her bedroom, shuts the door, looks for the phone - it isn't there in its cradle - so she lifts a guitar and charges back out]
Sam: Get out of my fucking flat!
[a couple of them glance at her, make derogatory noises because they're too busy worrying about the situation, and turn away]
Sam: I said, get out!
Moses: Yo, snitch. Calm yourself. This ain't about you no more.
Sam: Come anywhere near me, and I swear I will scream this fucking block down!
Jerome: There's worse things out there to be scared of than us, tonight! Trust it!
Dennis: Hey, bruv. I saw her ID card thing. She's a nurse, innit?
Pest: Help me, then! I need this leg. I need it to be able to run away from them things!
Sam: You think I'm going to help you? After you attacked me and robbed me, and then set those dogs on the police?
Dennis: Yes to the first two, no to the last one.
Pest: Dogs? What kind of dogs those? Dogs with no eyes? Dogs the size of gorillas? You think them things are dogs? Go out there and try feeding them some Pedigree Chum! They're ALIENS, luv!
Sam: Whatever the fuck they are, they're not fucking aliens!
Dennis: You swear too much, man.
Pest: Yeah, you got a potty mouth, man.
Jerome: Look, whatever they are, they're inside the Block now. They're after everyone.
Dennis: Yeah. We're on the same side, man. Get it?
[last lines]
Sam: [to police officers] I know them. They're my neighbors. They protected me.
[Moses is being taken away by the police, because he had weapons he used against the aliens, and the neighbors become a crowd and start chanting, "Moses! Moses! Moses! Moses!" Both Moses and Pest are handcuffed inside the police wagon]
Pest: Moses, brother! Can you hear that? That's for you, man.
[Moses, his face still wounded by an alien, hears the chanting of his name; he looks up and smiles]
Brewis: Believe me, I'd go out there myself if I wasn't so profoundly stoned.
Sam: We should call the police.
Pest: You'd be better off calling the Ghostbusters love.
Brewis: [while being arrested] I know my civil liberties, I'm a member of fucking amnesty!
Pest: Big alien gorilla wolf motherfuckers. I swear.
Biggz: Hurry up guys, we gotta catch 'em all!
Pest: Calm down Biggz, this ain't Pokemon!
Jerome: This is too much madness to explain in one text!
Dimples: What kind of alien, out of all the places in the whole wide world, would invade some shitty council estate in south London?
Dennis: One that's lookin' for a fight!
Ron: Well, 'ere, lads, you've discovered a species hitherto unknown to science, quite possibly non-terrestrial in origin, and you kicked its fuckin' head in!
Ron: Even if it is an alien invasion, they're four foot high, blind and got kicked to death by a bunch of kids. We got nothing to worry about.
Pest: I've got nice boxers on. Genuine Calvin Klein. Fresh today.
Brewis: Well, whatever it is, you're covered in it and it seems to be piquing the interest of a rather hostile alien species. I'm just saying... maybe if you took those clothes off, they wouldn't know we're here.
Pest: You fancy him or something? Are you trying to get him naked?
Brewis: I'm too high for this shit!
Probs: No one is going to call you Mayhem if you keep acting like such a pussy!
Brewis: [to Pest after being accidentally hit in the face] The fuck was that for?
Pest: Call Simon Cowell. Aliens Got Talent.
Brewis: Jokes man, jokes!
Hi-Hatz: I was gonna make you. Now I'm gonna dead you. This is MY block!
Brewis: Someone, like, petrol-bombed my dad's car. And there are po po everywhere!
Pest: That's an alien bruv, believe it.
Biggz: It was like some Gears of War thing!
[finding Pest in danger of being torn apart by an alien]
Sam: Follow me!
Biggz: I'm killing 'em, I'm killing 'em straight.
Jerome: I'd like to see the brother who's going to fight that.
[first lines]
Sam: [on phone] Hi mum!
