Good find! Must be a jewish thing, lil dicky (featuring snoop dogg) has the pizza reference "jerking off to boy meets world, 14 year old topenga" while eating pizza at 2:55

Yes I nearly made this post myself.

A couple of other things I noticed in the subtext of the movie:

-His wife is an artist, who while engaged in modern art mostly does innocent self expression. When the girls show up however, they defile her art projects with lewd, sexualised graffiti and vandalism.

-The girls are in fact legal age, but in their harrassment of him, they convince him that they are under age, and they use this as a kind of both emotional and literal blackmail. (Spoilers - they eventually threaten to post his sex with them on his Facebook account)

-This one is not pizza related but an interesting bit of subtext - the first time the girls appear is when he's sitting at his computer alone, trying to focus on his work. Then he offers the girls a tissue. (there are other instances where he offers the girls a tissue) I think this might suggest that he is in fact fantasising about this encounter, and it's a symbol of using tissues after looking up porn on your computer.

Anyway, good post, I definitely think there's something to this.

Also, consider that the director Eli Roth also made the film 'Hostel' which is about kidnapped torture victims whose lives are auctioned off to wealthy elites for the sake of torturing for their own gratification.

Check out the Extras on the Blu Ray - the making off - has the co-writer/ producer saying "if free pizza comes to your door you wouldn't refuse it" [paraphrased]. As the movie is about underage sex basically he is confirming that Pizza is code word for young girl and its OK to have sex with an underage girl if its on offer. The extras, including Kenau Revees interview, are the most in your face Hollywood/pizzagate example I have found.
