Bitchtits? Sounds horrible. I just use words like my tits and ass. I don't get too clever when referring to them.
You can borrow sugar tits if you like And I don't like bitchtits either...sounds like something exchanged between guys in federal pound you in the ass prison.
sugarbottom...That is such a cute word...lol...I like it a lot. I think I'll use it the next time I'm with a customer at work.
