Explain Big Brother Slop?!

Explain Big Brother Slop?

Can someone please explain the "food challenge" on Big Brother. They say that the loser has to eat "slop", but I've been watching Big Brother After Dark and everyone is eating all kinds of stuff -- including the people who are supposed to be on slop. They also have that big snack room. I don't get it.

BB slop is real. Sometimes they have to go on slop for a week if they have lost a challenge...however, sometimes you can win a "slop pass" in certain challenges that allows you to eat normal food.
On the showtime feed, you was watching them eat pizza last night assume?...its because they had just been taken off the slop punishment.
Everyone follows the house rules when it comes to food. There are cameras everywhere, so anyone sneaking and eating something they are not suppose to eat would be highly unlikely. They would get caught by a housemate or the camera.
There is a "snack room"...though its not really the kind of snack room like at work or the hotel.
It is their food commissary. The show places the food allotment for the week in that room. If the house guests go over the allotment, they go without until the next stock shows up.

Out of 8 seasons, I would have to say BB is the most real reality show there is. The house guests do the voting, there is 24 live feeds showing their every movement, you don't have to rely on America voting and wondering if the producers are lying about the results. Its all there right in front of you.
Have fun.
