Oxymoron for instance " jumbo shrimp"
I believe the answer to this question would be either a metaphor, idiom, or alliteration. But this would most likely be idiom because people can interpret different meanings of this phrase negative or positive and can take it personally or extensively.
The most important will be the following:
-The ability to get along with others
-Intellectual Brilliance
-Curiosity
