Buffy said it to Angel..."What? Are you twelve?" I think it was Gunn that Angel spoke to just after the fight in Destiny. He said Spike won because he wanted it more. Gunn made the remark that it was a fake reward that cup of Mountain Dew. It wasn't the cup that Spike wanted. It was to finally get to say everything that had built up over the years. He was right. Angel beat Spike down so he could feel better about himself. And,yes, most men are like little boys in how petty they can be.
