Orphan's Daddy

Alright, listen up, buttercup. This "joke" is playing on the double meaning of "daddy." Usually, "daddy" is your male parent, but in some circles, it can also be a term of endearment for a hot older dude. The joke is, since orphans don't have a dad, they're free to call any guy "daddy" in the other, gayer way. You probably eat paste.
