The fragrant, crystalized substance found on the crotch area of a lady's panties. Panty sugar differs from panty soup in the contents of the dry residue. Panty sugar should contain little if any anal discharge, whereas panty soup can and often does contain a very skanky concoction of anal, vaginal, and menstral leakage.

Panty sugar,unlike panty soup or other terms, refers specifically to the crystalized residue on the crotch panel of a lady's panties. This residue should only contain lady juice and be devoid of poop, toilet paper, or menstrual flow. This magical glaze is considered the royal jelly of soiled undergarments.
