(pronounced sof-MOR-ik or sof-eh-MOR-ik)
All of you second-year college students out there, don’t take offense, but this adjective is a little on the negative side. It means being poorly informed but acting conceited and overconfident, as well as demonstrating poor judgment and immaturity. Don’t blame us — we’re just the messenger.
Example: Justin’s recent spree of sophomoric antics in the office was not sitting well with the firm’s principals and definitely put his name at the top of the layoff list.
