前几天和小女一起刷碗，无意中说起了“pretty sure”这个词组。让她把sure， absolutely sure，和pretty sure排个序，小人儿说：“pretty sure，sure，absolutely sure。”我很奇怪的问，“pretty sure不是应该比sure更sure吗？”她说，“No，pretty sure is not quite sure。”我抱着非常怀疑的态度用力google了一下，urban dictionary中说：

When a piece of shit doesn't know what he's talking about but wants to make it sound like he does without facing penalty of being incorrect. S/he hides behind of veil of faggotry for protection from persecution by his/her peers when it turns out they're wrong by precursoring something they can't guarantee by saying "I'm pretty sure".

原来这几十年国内国外的全部都用错了? 难怪别人对我说这么不信任。。。难怪我总奇怪人家怎么都这么自信。。。唉。。。
