If you don’t know what pocket we’re talking about, head to your underwear drawer right now and take a look at some of your panties. We can almost guarantee that most of the pairs of underwear in there will have a little flap right at the bottom where your, achem, lady parts go.
This pocket—which actually isn’t even a pocket at all—has a name, and it’s called a “gusset.” Some people also refer to it as a “crotch lining,” but for the sake of our appetites, we’re going to keep calling it a gusset. A gusset is defined as “a triangular or rhomboidal piece of fabric inserted into a seam to add breadth or reduce stress from tight-fitting clothing.” In other words, it’s a little piece of extra fabric added to underwear to allow your nether region to breathe and protect it from any harm.
