I used to, but now I just say frick or sugar... or I just make up some random thing that begins with the same letter of the swear I was going to use... if I was to type it'd look something like, "Ffgftrtg!" Yes, I speak spam... Although the other day in school my teacher was walking by and I knocked some glue off the table... I automatically said, "Oh -bleep-," but I said the f word and I can't post that here. xP ...They told me they hadn't heard me after I'd apologised.
