A phrase by Phillip Schofield during his show with Jamie Oliver. Jamie Oliver said to put salad into a pasty (British pastry that can only include meat, onion, salt and pepper), thus surprising Phillip Schofield.
Jamie Oliver: If you open up a little pocket and shove some of that salad in there ...
Phillip Schofield: SALAD IN A PASTY, YOU FILTHY PERVERT!!!
A promiscuous females vagina. Salami being a common food based reference to a penis and pantry being a storage unit where dry non-perishable food goods are kept combines to create a relevant metaphor for a vagina that plays common host to penis.
