Trajeck

Trajeck is what a Mary Sue with an overly traumatic past has. It is related to 'tragic' in the same way that 'speshul' is related to 'special', in that someone with a trajeck past has a past so traumatic that it gets irritating.

Trajeck Sues often have the same trademarks: abusive family, dead family, dead girlfriend, ran away from home, the works. Except that it is not actually tragic, since it often gets used as nothing more than a plot device.

Expect a Sue with a trajeck past to either ignore the "trauma" completely or engage in copious amounts of wangst.
