McSteak 

Back in the day when you used to add Mc infront of alot of words - this word managed to last the test of time, McSteak is another word for mistake.

It's also funny because whenever McDonalds brought out a steak burger it was always terrible.

Beckett: Max did you try and pick up that Montenegrin girl last night?

Max: Oooooooh what a McSteak that was, complete waste of time as per usual.

She’s extremely pretty and has a body of a goddess but she’s a whore with the worst attitude you could ever imagine. she smells like expired fish fingers and guys think her pussy tastes like sour milk and liver. she talks shit about anything that breathes and nobody likes her stank ass. she’s a snake and even Regina George wouldn’t approve of her. don’t trust her.

“some Sneaky McSneak-Sneak Bitch told me that your boyfriend fucked her!”

Person 1: why does she always talk shit about people she doesn’t know?!
Person 2: ah don’t worry, she’s just a classic Sneaky McSneak-Sneak bitch
