You know what black pepper looks like? Well imagine going into the bathroom and looking at the seat and you find what looks like pepper sprinkled all over the surface. If it's a special day, you might also see pieces of pubes too! This is most common in female bathrooms and come from dirty girls who leave presents on the toilet seat for other people to find.
Damn! She's hella dirty. Pepper cooch for real. She just left it all over the seat. *barfing noise*
