bpeh
the residue that is left on panties after a girl is done with her period and has stopped wearing tampons or pads usually a brownish color and a very heavy and disgusting scent for the most part it might be sticky but it's usually because it mixes with discharge. although bpeh is not common with some girls it does secrete when the female lacks vaginal sanitation or if she does not change her panties while on her period.
