Sunderwear 

Cotton panties or underwear that have been farted in so many times that the fabric near the anus becomes partially transparent to the point where the spot is distinctive.

Sunderwear is never shit stained nor is it created by direct contact with poo matter. Rather it is created by the various chemicals in the fart acting upon the underwear fabric.

he sure does, i bet he has a whole drawer filled with sunderwear.

slunderwear 

A pair of particularly scandalous or slutty panties; like the tiny, black lace, completely see-through ones that you feel awkward washing with the rest of your clothes because they are just that sexual, or Heaven forbid you use a public laundry room and they should fall out of the pile onto the floor before a crowd of judgmental eyes...or your mom.

Kathy made the unfortunate mistake of wearing slunderwear under her dress on a breezy day.

Skunderwear 

Skunderwear:
A skirt or skirt so short that it would function successfully as an undergarment.

It was quite evident that the lady golfer in the 9th tee, was wearing skunderwear and hence, distracting her less able male compatriots.

Scunderwarf

A scarf made of used underwear.

I was cold, and on a leasurely jaunt with my lady friends, and to aid my temperature driven ailment they all removed their pants, and tired their underwear into a scarf. So I was all like, "Thanks for the scunderwarf."

Shunderwear 

Underwear that should have been thrown out but remain in your drawer because they never fail to save your ass.

I haven't done laundry for over a month, so today I was forced to bust out the shunderwear.
