Harry: He claps his hand over your mouth, frowning. "Y/N! That was naughty. You're too sweet to be swearing. Now say sorry." He makes you apologize every time you curse, and if you don't, he refuses to kiss or hug you until you do.

Zayn: Zayn thinks it's incredibly hot when you swear, which gets him into trouble sometimes. When you're mad at him and begin cussing him out, he'll try to kiss you, just making you even more mad, and causing you to cuss more.

Louis: "Do you kiss your mother with that mouth?" he chuckles. "Well, you can still kiss me. I don't care if your mouth is dirty. I've got plenty of gum," he says, drawing you close and pecking you on the lips.

Niall: He's a bit of a potty mouth himself, and he tries to not curse around you as much, but sometimes he slips, and the habit has rubbed off on you. "Christ, your mum's going to kill me," he mumbles after you let out a stream of particularly colorful words.

Liam: Although he usually disapproves of swearing, he thinks it's adorable when you do, since you're usually so ladylike. He'll reply with one of his own "swear words," such as fudgsicles or poo, making you laugh.
