Ageist term dehumanizing and stereotyping persons between 13 and 19. Sometimes used to avoid logical argumentation or dismiss emotions.
Teenagerdumb is the state of thinking you're invincible and know everything. The majority of teenagers think so, will stop thinking so just as they'll stop being teenagers, and no adult thinks such things.
