deintroversive (adj.): having the quality of energizing introverts, generally applied to a person--John is deintroversive; I enjoy spending time with my deintroversive friends.
Origins: Eastern Ohio River Valley, 21st century. The term derives from the fact that introverts, although not opposed to socialization, generally find it tiring and have to "recharge" afterwards. However, when socializing with certain people an introvert will find herself energized. These people are deintroversive to her.
