Armor-Piercing Slap/Playing With

Basic Trope: When a girl gets pissed off, she will slap the guy who did so, and it will hurt, no matter how strong he is. "Alice: Wow. Didn't know I was that strong. Bob: (withering in pain) Neither did I...!"
 * Straight: When Bob forgets Alice's birthday, she smacks him. It hurts quite a lot, despite Bob being very strong and usually resistant to pain.
 * Exaggerated: While he's wearing seven layers of armor.
 * Downplayed: The slap hurts a little bit, but it's more like a minor annoyance.
 * Justified: Alice is just that strong.
 * Inverted: Alice's slaps never hurt, even though Bob is a weakling.
 * Subverted: Bob was just pretending, since he knew that if it didn't hurt, Alice would do something even worse.
 * Double Subverted: At least that's what he says to protects his ego.
 * Parodied: Bob is the strongest man in the world, but a slap from Alice -- who is about a foot tall-- renders him powerless.
 * Zig Zagged: Whether or not Alice's slaps hurt depends.
 * Averted: Alice's slap doesn't hurt.
 * Enforced: "We need something to show how strong Alice is."
 * Lampshaded: "How did that hurt you? You have on seven layers of armor!"
 * Invoked: Alice spends years learning how to slap people so hard, it hurts no matter how strong they are.
 * Defied: Alice refuses to slap people who could pummel her.
 * Discussed:


 * Conversed: "Have you ever noticed that girls' slaps always hurt, even on super-strong guys?"
