A semi-slang term used to describe one extreme of of possible possible of a woman's labia minora. It is characterized by a wavy shape of the labia with many wrinkles and fine crevices.

The opposite extreme is referred to as "rose petal."

It is important to note that while current fashion tends to favor labia near the rose petal end of the spectrum, there is nothing "gross" or "weird" about roast beef. Every vulva is a unique and special part of every women.

Other terms that describe the form of a women's labia include "innie" and "outie," both referring to whether or not the labia minora protrude from the labia majora.
Be it roast beef or rose petal, it's the texture inside that counts.

Hawt tasty vagoo that i'd love to suckle and play with all night long.

Contrary to popular belief, roast beef is a prized treasure a girl is born with, much like big tits, rather than a grotesuqe result of overusage.

When she pulled off her panties and the roast beef popped out in front of my face, i jizzed myself immediately.

The luscious protruding inner lips of a woman's vagina which is men’s favorite part to suck on during oral sex.
These inner lips are particularly sensitive and touching them makes the woman orgasm.
The inner lips of some genetically blessed women grow larger during puberty.
The inner labia of the majority of women more or less protrude beyond the outer labia but since the protruding lips are considered too sexy (too graphic) for soft porn, the guidelines mandate digital removal of these parts before getting them published. So virgin guys who are used to jerking off to porn pussies are not aware of this trait of real-life pussies.
1.My girl’s roast beef lips can kiss my dick at the same time she’s kissing my lips. It makes me and her madly horny!!!

2.I love rolling my wife’s roast beef lips around in my mouth. Sucking on those juicy pussy-lips sends me and her to heaven!

3.Mike doesn’t know how sex works. I laughed so hard at that virgin dude when he said he thought girls can get their roast beef lips stretched out during sex hahaaaaaa
