1. A very popular 'old school' dish in London, namely the East End. Consists of a Pie containing just Minced Beef and a serving of Mashed Potato. Commonly covered with 'Liquor' (Pronounced 'Licker'), which is an almost flavourless sauce consisting of flour, water and parsley.

2. Cockney rhyming slang for 'Slash', meaning to urinate.

3. A slang term for 'Gash' referring to the female genitalia. Although in this case, it is used to refer to any type of sexual contact with a partner, not just 'Gash'

London, UK.
Historically, the pies were made from scraps of beef and vegetables, leftovers or from the local markets, under a pastry crust. The mashed potatoes were liberally covered in parsley gravy or "liquor". There has been a great revival in these dishes and quite a number of Pie ‘n’ Mash restaurants can now be found across London.
Traditional foods in London include pie 'n' mash and jellied eels.

The aftermath of what you believed to be a humble fart.
1. Peter thought he was clever performing a one cheek bench sneak but didn't feel so fucking clever when he realised he had Shepards Pie without the Mash in his pants.

2. "That fart sounded wet" Steve announced during the Sermon
"Feels wet actually Steve" replied the Vicar, "I do believe I have Shepards Pie without the Mash in my underwear, please excuse me while I clean this shit up"

3. Deidre suddenly became withdrawn & pale. It was clearly obvious she had Shepards Pie without the Mash in her knickers.

4. Dave let out a thunderous bottom belch and grinned insanely, "Shepards Pie without the Mash" he exclaimed
