I never bought used panties, but during High School, I was the jock who played D&D. I was pretty popular, did well in school, dated the foreign exchange student, and defended the kids who were bullied. High school was awesome for me and I had a couple fan-girls (if they saw me now, they'd laugh).

One day after school (back in the late '90's) I was watching anime - I think it was new Ranma 1/2 episode with a Haitian dude who we used to call a nerd, but would probably be labelled a weeabo now.

I got a knock and run. There was cardboard box on my doorstep with my name on it. I took it inside and opened it. Inside was a note and a pair of silky men's underpants, like Speedo, cup-your balls type undies.

Maybe it was a speedo swim bottom, maybe it was underpants, and I think it was red, but it was a long time ago. What I do recall is that I was an asshole and tackled the Haitian weeabo kid and forced the underpants over his head and said something like, "You will test if there is itching powder in these!" (I know it seems hypocritical, since I said I defended these guys, but as a teenager, I defended them from exterior bullying, but did do a little bullying of my own - out of ignorance, not maliciousness. 20 yrs later, I still talk to some of these guys).

I think I saved them for a while. But I trashed them by the time I went to college. Oh - the note... The only thing that I can really recall was part of one line that was really cheesy: "your firmly toned loins." I think the use of the word "loins" is why it stuck with me.
