Tolossa (n) is a
name you can give to someone very proud of his/her identity. Tolossa people will not pretend to be someone they are not even if pretending would have been beneficial at the moment. As such they are not good for acting roles.
The origin is a TV evangelist's episode in Ethiopia where the evangelist told a congregation member the latter has a new
name now. When the evangelist asked "What's your
name now?" the guy responded with his original
name "Tolossa" instead of playing along and saying the new anointed name.
