A Guillaume

The art of wiping out a system or entire infrastructure or company in 1 simple command.

Jonathon: "Boss, All of the systems have gone offline, nobody can take any cash out of the cash machines. Literally, they are all broken"
Boss: Who the fuck has done a Guillaume?

Wendy: Boss, do you mind if I jump in there and just update it myself cos IT are busy?
Boss: We do not need another fucking Guillaume on our hands.

Guillemette

Guillemettes are some of the nicest, most selfless, and empathetic girls in the world. She will always stick up for you and is loyal until the very end. When you need a shoulder to cry on, she's there. When you are laughing so hard that you might run out of air, she will be there to laugh along with you. Though all of these amazingly spectacular traits exist within her, she has a dark side too. She may not mean it, but sometimes she makes everyone around her feel invisible and insecure. She changes those around her for the better and for the worst. You are lucky and cursed to ever meet a Guillemette.

Guillemette and I are going downtown tomorrow with friends.

Girl1 : which characters ? In Which series?
Girl2 : Tommy Shelby in Peaky Blinders and Harvey Specter in Suits
Girl1 : OMG !! That's completely true
Girl2 : he could be a Guillaume isn't it ?
