And nor does it literally mean "Older Than Dirt". Dirt predates life, so since life is required for tropes to even exist, there were no tropes back then except a handful of Unbuilt Tropes which have nothing to do with any form of life, or dirt of course.
Older Than Steam does not reference things that are of a greater age than Valve's online content delivery service.
Open the Iris is not an order to lower the Stargate's defenses to allow travelers into Stargate Command, nor about doing naughty things to a◊ girl◊ named◊ Iris◊. Nor is it about time-lapse photography of flowers blooming.
It's also not about performing surgery on a particular nun in Phoenix Wright Ace Attorney: Trials and Tribulations.
Its also not a strange command to get people to open their eyes.
Pimp Duds are not incompetent panderers and procurers.
Pimped-Out Dress is not about pimps who like to crossdress. Nor is it about ball gowns with hydraulics and rims (but this would be AWESOME). It's not even about clothing worn by prostitutes.
A Piñata Enemy is not the stick used to hit the piñata with.
Pinball Protagonist is not what happens when you make arcade games the main character. It also doesn't involve the tendency to turn popular characters such as Sonic, Kirby, Mario and Samus into balls and smack them with flippers.
A Player Nudge is not that thing little kids (and particularly immature teenagers and adults) do where they intentionally bump up against the players next to them while playing local multiplayer to mess them up.
A Player Party will probably not run candidates for public office.
Portal Splat is also not a Splat based around having the Aperture Science Portal Device.
Porting Disaster is not what happens when a Ship docks, and one of the two characters cannot perform. It's also not about an unfortunate collision or destruction of a sea vessel, or what happens after a miscalculation during teleportation.
A Portmantrope need have nothing to do with Natalie Portman.
The Pose of Silence is not an index finger raised to the lips in a shushing gesture.
A Possession Sue is not a Mary Sue with powers to take over other people's minds and/or bodies (though that'd be far from unlikely a power for a Mary Sue to have).
Nor is it what you do when you take the person who took over your body to court. After all, possession is nine points of the law.
Reverse Shrapnel is not an Insecticon going backwards. Nor is it "lenparhs". Nor is it magically undoing the effects of an explosion.
Revolving Door Revolution is not about coming out of the doorway on the same side you went in. It is also not about having to position oneself in the vestible of such a door at the exact moment dictate by arrows.
Right Hand Versus Left Hand has nothing to do with masturbation. The trope also has nothing to do with the legal jargon about the right hand not needing to know what the left is doing to consist a conspiracy charge. No arm-wrestling tournaments, either.
Nor does it have anything to do with an epic battle between people of left or right-handedness.
Or about baseball or cricket, where there are a lot of professional lefties.
Rings of Death aren't the places where death matches occur. Neither does it have to do with a defective Xbox 360. It's also not when there is more than one Ominous Ring of Land, or a deadly videotape. And we know you feel clever for thinking back to that moment in the mid-nineties where you finally reached Knuckles's final boss in Sonic & Knuckles and he started firing deadly rings at you, and you're getting warmer, but no, that's still not quite it. What, murderous crop circles? Oh, for crying out loud. And if you're thinking of a circular Artifact of Doom, you're still off the mark.
Road Runner PC is not about censoring Wile E. Coyote's "deaths". Nor is it a licensed game for home computers. Nor is Time Warner Cable offering a free computer in exchange for a 24-month contract, as some ISPs did during the dial-up era.
While there is a Robeast, there is no Robwest, Robnorth or Robsouth.
Robosexual is not about people who are sexually attracted only to robots.
A Rollercoaster Mine is not a mine on a rollercoaster track, nor is it a mine that when stepped on lobs the person in question into the air. Nor does it involve a young child who insists that only he can ride it.
