Teens: Do You Curse?

i curse all the time, but i limit it when i'm with my parents. me and my siblings go "yo, n*gger!" when we see eachother (we're all mixed race) and it's kind of funny, we do it to other black/mixed people and they take it fine. i use f*ck and sh*t and b*tch most, and words like w*nker and b*stard rarely. i never say c*nt, my parents would murder me. i do it in public and in private, and usually i say it because i'm frustrated, i'm greeting a mate or i've hit myself by accident (likely to stub my toe) and then yell "oh you f*cking sh*t b*tch!" ...but, meh. i don't curse as much as i used to.
