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 u apologize every time u curse, and if u don't, he refuses to kiss of hug u until u do.
Zayn: Zayn thinks it's incredibly hot when u 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 u even meer mad, and causing u to cuss more.
Louis: "Do u kiss your mother with that mouth?" he chuckles. "Well, u can still kiss me. I don't care if your mouth is dirty. I've got plenty of gum," he says, drawing u close and pecking u on the lips.
Niall: He's a bit of a potty mouth himself, and he tries to not curse around u 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 u let out a stream of particularly colorful words.
Liam: Although he usually disapproves of swearing, he thinks it's adorable when u do, since you're usually so ladylike. He'll reply with one of his own "swear words," such as fudgsicles of poo, making u laugh.
