I have a mouth that would make a fucking sailor blush...... LOL
HOWEVER, if I am around clients, or just people that aren't into that, then I DO have the ability to watch it and not talk so nasty..... but let me around someone that is cool with it and my mouth goes into high gear...... 
Working with/around men all my life, a girl has to fucking know how to deal with them...... right?
