An extroverted action is an action not normally performed on oneself or on each other (contrasting with introverted action).
extroverted event (SEM) / verb (CXN) = an event not normally performed on oneself or on each other; and a verb expressing such an event. Examples: seeing something vs. one-self, or loving someone vs. oneself (or even each other), are instances of extroverted events, and see and love are extroverted verbs. (Section 7.2)
