He made some posts about opening up underwear in big box stores, smearing precum on them in fitting rooms, and putting them back.
He then said they were just fantasies of his, and not something he actually does. Which I do believe is true, but since he didn't actually write the posts in a way where that was clear at all, he was understandably slammed for it. He got very quiet for a long while after that.
(But really, most underwear is packaged so there's no way someone could do this without it being really obviously tampered with. Like IIRC he was talking about straight up white briefs that come in cellophane wrapping).
