WTF - Titty Sweat

Building off of my previous post, now I want to talk about something else the wife said yesterday which came as a shock.  We had been working in the yard for a while.  Although it was a little windy, the temperature was very nice.  Apparently the temperature was a little warmer than I thought because my wife announced she had "titty sweat."  WTF?  Really?  With your 3 daughters within 10 feet of you, you state you have titty sweat?  I told her that if she was wearing a bra, she might not have that problem.  This is when it got worse.  My wife asks our oldest daughter if she was wearing a bra and if she was sweating around her titties.  WTF?? I don't know what is to be said about that situation.
