1.
The sexual maneuver, where the penis is repositioned from the vagina to the anus very quickly during intercourse.
She was getting pretty loose and bored so I pulled the trapdoor on her.
or
Connor that bastard pulled the trapdoor on me last night!
2.
a booger, usually quite dry, that is neither in or out of your nostril. When you breathe in the out the "trapdoor" booger opens and closes.
Sheila: Damnit! I got a trapdoor and I can't seem to reach to pull it out! I need longer fingernails!
