Give sb. the Cold Shoulder 对某人冷淡,冷眼相待

G：Sunshine, you got a bad case of puppy love?
J：Adam Smith needs revision.
M：What are you talking about?
J：If we all go for the blonde we block each other. Not a single one of us is going to get her.
So then we go for her friends but they will all give us the cold shoulder because nobody likes to be second choice.
Well，what if no one goes for the blonde?
We don't get to each other's way and we don't insult the other girls.
That's the only way we win. That's the only way we all get laid.
