A vagina belonging to a woman of unreasonably high standards. Not necessarily stuck up, just having such demanding standards that no one meets them, and consequently the gold plating on her gap tarnishes because she never gets laid.
"You snotty cunt, you totally have a gold plated gap, no one is good enough to stick it. So don't bitch to me about how you need to get laid."
"Dude, don't even bother with her. She has a gold plated gap."
"Dude, don't even bother with her. She has a gold plated gap."
