A social outcast is someone who is not accepted by society and is often seen as an outsider. The term can be broken down into four words: LEPER (5 letters), NERD (4 letters), PARIAH (6 letters), and MISFIT (6 letters). A LEPER is someone who is shunned due to a contagious disease, while a NERD is someone who is socially awkward and lacks social skills. A PARIAH is someone who is rejected by society and is considered an outcast, and a MISFIT is someone who does not fit in with the norms of society.
