Keep playing me you're gonna end up with a huge goose egg
Two meanings for “goose egg” here (and they both suck). It can be used to describe a giant bruise, like the one Em is going to give this girl if he catches her cheating. Or it can be used to mean “nothing”, because if Em leaves her she will have nothing after.
