1. An Overly hairy vagina with large, brownish, floppy labia.
(Think Arby's Roast Beef) Refers to Cuban leader, Fidel Castro, who has thick, coarse beard. Like most beards, could be mistaken for pubic hair.
2. Fidel Castro, leader of Cuba, feasting on a sandwich of roast beef.

An incredibly accurate, culinary description of what the average African American woman's vagina looks like suffering from a yeast infection while on her period. Her vagina's dank and musty, dark purple meat flaps are almost indistinguishable from Arby's delicious sliced ROAST BEEF and oozing from them like Arby's yummy warm CHEDDAR cheese sauce is the untreated slop of rancid chunky bacterial discharge churned together with dark brown coagulating menstrual flow...which is of course Arby's amazing RED RANCH sauce!
If Michelle Obama had a vagina and could have a heavy period and get yeast infections then his Vagina would look like a roast beef and cheddar with extra red ranch. But she's a dude so....ya.

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.
