Please. Have you people no sense of the absurd?
Obviously this is a commentary on the practice of selling used panties or thongs via Craigslist. Generally the ad may include a picture of a very shapely and inviting derrière wearing the afore mentioned under garments and a promise that they were indeed worn by the pictured buttocks. There may also be an offer of removing them in person, perhaps in a vehicle, alley way or some other semi private place; but with the strict understanding that there will be absolutely NO sexual contact whatsoever. Not even a HJ.
I, for one, would like to take the opportunity to express my thanks to "goo" for his startlingly accurate critique of the many forms of pseudo-sexual services offered in the online community.
Bravo sir, bravo.
