Yo, I was makin out with this girl Aisha at a party earlier but Larry, this dude who was one of her friends, wouldn't fuckin leave the room. Some cops came and larry tried to bolt cuz he was holdin. Larry got arrested and left with the cops and I fucked the shit out of Aisha. It was like sweet cherry "pi" up in that shit! Now thats a fuckin elimination reaction.
