Snape-killing 

Killing someone to deceive your dark overlord into believing you are their greatest agent.

We thought he was a bad guy at first, but it turns out that he was just snape-killing his ally.

Killing Two Stones With One Bird 

Phrase uttered by Hong Kong Chief Executive Carrie Lam at a press conference. Pretty much sums up how illogical her policies and decision making can get.

With these quarantine restrictions Hong Kong will never reopen borders with the outside world or economically recover, killing two stones with one bird.

Killing Eve 

An awesome BBC America dramedy television show about two women---a detective, Eve, and an extraordinary assassin, Villanelle, becoming obsessed with each other (to the point where you will wonder if it's romantic interest) as they try to take each other down. The acting by Sandra Oh (Cristina from Grey's Anatomy) is great and Jodie Comer will especially wow your ass.

Season 2 will come sometime next year.

Killing Eve: BBC tv show

Eve: “I think about you all the time. I think about what you’re wearing and what you’re doing and who you’re doing it with. I think about what friends you have, what you eat before you work, what shampoo you use, what happened in your family. I think about your eyes and your mouth and what you feel when you kill someone. I think about what you had for breakfast. I just want to know everything.”
Villanelle: I think about you too. I mean. I masturbate about you a lot.
Eve: Okay... that's...
Villanelle: Too much?
Eve: No... I just wasn't expecting that.

Millering 

Having different drinks in front of you at once.

Why do you have all of those drinks.
I have a white wine for the fish, a red for the steak, a champagne for the toast and I'm just finishing this beer.
Oh so you're Millering.
