"bring me something cold to drink bro, those things are fuckin hot! ... little shits"
A guy's roommate is dating some girl, and she keeps bringing her friend over, so he and the friend hook up. He doesn't really like her, but she's always just around, so what the hell.
Compared to, if you wake up the morning and you want to eat something really good or healthy, but you find out there's a plate of pizza rolls left in the microwave for you, you sort've give up on the effort of something you want and just eat the crap, because it's convenient and there.
