Jinx has a negative connotation. If you were jinxed, you would have no job offer, lightning struck your body as you returned home, a criminal robbed you while you were paralyzed, and you came home with a permanent pterodactyl voice.
It was in reference to my earlier post about how I was going to have some freedom because today was my last day for my work term. Tsuru said I shouldn't jinx myself. =P
also... I think I know some people with a permanent pterodactyl voice....
