Hate it.
My missus curses all the time. I’m forever telling her off for saying feck and for fecks sake in front of the bairns, she’s Irish and yes lives up to the stereotype.
My dad who’s also from Irish parents effed and Jeffed like hell growing up. I was 20 before I heard my mother swear and that was because she dropped the turkey on Christmas Day taking it out the oven and the dog pounced on it (genuine story)
My first wife once burned her hand on the oven and regaled her young nephews with the magnificent AH YA f***ing COCKSUCKER!!
