The Key Fits The Lock 

A saying used about small-penised paedophiles

The key - small penis
The lock - the underage (and therefore illegal) vagina of a girl under 16 years of age.

A: That guy is a nonce - he has a small cock too, can't handle a proper relationship with an adult
B: In his case, the key fits the lock

Pink pussy hat wearers

History Remembered: Trump and the Locker Room Ladies

In an infamous Access Hollywood hot mic moment, Trump expressed his amazement and dismay with the type of women that will allow famous men to fondle them just because they're famous. This criticism did not sit well with what we'll call "the locker room ladies" who in protest chose to strap on pink ski hats intended to resemble female anatomy so as to say we'll use our female anatomy however we want thank you very much and how dare you even comment on our behavior. To show just how serious they were, they then proceeded to vote for history's most famous fondler in the 2020 election. This has been history remembered.

picking the lock 

When two Asians are having sex, one will use chopsticks on his/her female partner. Using one to manipulate the clitoris and the other to apply pressure to the g-spot.

Asian 1: can you leave? I'm picking the lock on my girlfriend.
Asian 2: okay man, I'll leave.

lock the knucks 

Make hooks with your hands and lock them together in an opposing fashion so your elbows stick out.

When the army of giant fire ants attacks the villagers, lock the knucks and ride the human wave with your bows out to escape with minimal effort.
