This Time Travel Trope is a specific form of Grandfather Paradox. This version disperses with all the baggage of causality and paradox, and just happily declares that being your own ancestor is perfectly normal. Milder versions involve that old drifter or shadowy figure from your childhood that saved your life, or set you on the straight and narrow, and whom later turns out to actually be your own future self.
Basically, this trope says Temporal Paradox and mucking around with your own origins is just fine and dandy. It seems to absolve the time traveler of all moral culpability or ambiguity. Going back and interfering with the circumstances of your own childhood or origins will result in a Stable Time Loop.
The Mild version appears in Terry Pratchett's Night Watch, albeit as a repair for a temporal paradox.

- This certainly makes for a lighter campaign style than the dreary self-hating types suggested by Autoinfanticide, or the queasy unsettling implications that might otherwise come up from the Grandfather Paradox.
