In my head, quite a bit. Outloud, if I'm mad. If I'm texting someone I'll make references to the Big Bad curse words when I'm mad but I don't out right text them. I'll text out the smaller less 'bad' ones thou.
People would get so surprised when I did curse outloud but also they would find it funny so I try to not say curse words around others so I don't make myself look like a fool when I'm clearly ticked. The last thing I want is for people to laugh at me when I'm cursing, since I'm tryin to make a point that since they got me cursing then I'm real mad.
