Referring to loose labia, also known as pastrami curtains because it can be easily blown around in the wind. However the term "Roast Beef" is generally for women whose snatch is more brown then pink, and the lips stick together like a grilled cheese sandwich. As age starts to progress, their meaty flaps start to dangle and look like two slabs of roast beef stuck together with mayonnaise, thus the term "Roast Beef Snatch."
I fucked this cheerleader the other day and her roast beef snatch looked like it went through a meat grinder.
