Rezierre 

A Rezierre (or a Rez for short) is the type of guy to time travel five years back, have sex with his past self and impregnate them, wait until they give birth, then kill their past self, impregnate the baby, and through a time paradox will be reborn as that baby's child to start a new life.

"Hey dude, why isn't Josh here?
"He's off studying quantum physics, the dude is such a Rezierre"
