A "dilated pore of Winer" sounds like a mysterious land from The Phantom Tollbooth, but according to Someecards hero Sandra "Dr. Pimple Popper" Lee, it's the name of a really, really gross type of blackhead (seriously, don't Google image search this). "They are often dried up, sticky, and difficult," said Lee on her blog, "but very satisfying and gratifying to remove." You'll take her word for it after watching this video, which is genuinely kind of disturbing.
