A moist and creamy but partially solid discharge that can be found lining a womans panties or just within her vulva. Often associated with a smelly pum.

Visually very similar to small pieces of feta cheese but slightly more creamy.

Trout crumb has a high probability of drying up and going crusty when outside of the vagina.
I pulled down Charlotte's panties and they were lined with dried up trout crumb. Clearly she had a yeast infection.
