Shut up daddy

Also "Daddy Shut Up". A nickname applied on Television Without Pity to the deceased John Winchester, who has taken a lot of heat across the forums - and across fandom - and in the recaps for his actions (or non-actions) on the show, and oft perceived crappy parenting.

Ironically in 5.13 The Song Remains the Same, a young John Winchester dishes out on the way Sam's father raised him, proving that even John Winchester thought he was a bad father.
