楼上只对一部分。Odd one out (或odd man out) 是成语， 有几个不同意思：与众不同，最奇特的（方法），不同于其他的（东西），剔除一个，格格不入，等等。 例：1. The invitation was for couples only, so Jane was odd one out2. Please look at these five objects and tell us which is the odd one out.3. IQ Test: November is the odd one out because it has only 30 days. The months of August, December and January have 31 days each.
