Gussetfudge 

The nasty goo that gets left behind in some women's panties. Sometimes crunchy, sometimes chewy, but always worth a sniff or two..... lmao....

Goddamn, these bloomers are packin' a snatchload of Gussetfudge !

Gusset Fudge 

The crusty stains left on the gusset of womens underwear, due to the discharge and subsequent drying of vaginal juices. Usually of whitish appearance, it is sometimes a darker tan color, especially when the lady has a little bit too much cheese on the taco or is straight up diseased

I couldn't go down on her after I saw the gusset fudge in her panties
