In the movie "You, Me & Dupree", Dupree pulled off the Dupree in one of Carl's socks.
When a girls giving you head and you feel that she just cant seem to get the job done, and your dick is almost going limp, you just pull it out and slap her right in the nose with your cock making her nose bleed.
A girl was giving me head in my friends bathroom and was just horrible at sucking dick. My dick was almost limp so i decided to pull my cock out of her mouth and slap her in the nose with it making her nose bleed. She then jumped off her knees in shock, and i said calmly to her, you just got "The DuPree" bitch.
