High Schooling 

vi. When adults, in adult situations, behave as if they were in high school - teasing, bullying, forming cliques, generally being immature.

Don't go to work at Bill's company, only two things go on over there - working and high schooling. If you do go to work there, you had better get in with the cool crowd ASAP, or you will end being pushed around and stepped on forever.
