Heaven in a bowl

Dude, what the fuck is up with that white shit that they give you with the tortillas at a mexican restaurant? Not the gooey cheese, I'm talking about that spicy ranch-esque stuff. OMG! Went out for Mexican last night and now I just can't get my mind off of it. We were dipping everything we could find in that white shit. Fries, rice... I was tempted to dip my fingers in and bite them off, but I had just done my nails... Maybe I could be marinated in it when I die, or give birth to a child in it or something symbolic to show my love for it! If anyone knows what brand of crack they use to make that stuff, please let me know!
