A pariah is someone that has been soundly rejected by their community. Your constant gossiping might make you a pariah on campus.
Pariah takes its name from a tribe in Southeast India. The pariahs were drummers, sorcerers, and servants who became untouchables in Indian society because of the unsanitary jobs they did. Pariah maintains this sense of untouchableness. Pariahs are not just unliked, they are avoided at all costs. Imagine how a once popular restaurant could gain pariah status if it fails health inspections three times in a row.
